• Added New-ExcelStyle, plus -Style to Export-Excel and -Merge to Set-ExcelRange
• Added Style Examples

What's new 6.1.0

Thank you to James O'Neill

• Instead of specifying a path provides an Excel Package object (from Open-ExcelPackage), using this avoids re-reading the whole file when importing multiple parts of it. To allow multiple read operations Import-Excel does NOT close the package, and you should use Close-ExcelPackage -noSave to close it.

What's new 6.0.0

Thank you to James O'Neill for the optimizations, and refactoring leading to a ~10x speed increase. Thanks to ili101 for earlier PRs that provided the ground work for this.

• Performance improvement to Export-Excel see #506 and #555. This has meant taking code in Add-CellValue back into process block of Export-Excel, as the overhead of calling the function was a lot greater than time executing the code inside it. Blog post to follow. Some tests are showing a ~10x speed increase. #572 was about a broken #region tag in this part of the code and that has been cleaned up in the process.
• Export-Excel now has an -InputObject parameter (this was previously -TargetData , which is now an alias for InputObject). If the inputobject is an array, each item will be inserted, so you can run export-excel -inputobject $x rather than $x | Export-Excel, and if it is a system.data.datatable object it will be inserted directly rather than cell-by-cell. Send-SQLDataToExcel takes advantage of this new functionality. There are simple tests for these new items
• Export-Excel previously assumed -Now if there were no other parameters, it will now assume -Now if there is no -Path or -ExcelPackage. The .PSD1 file now itemizes the items exported by the module #557

What's new 5.4.5

Thank you to James O'Neill for the great additions.

• Modified Send-SQLDataToExcel so it creates tables and ranges itself; previously it relied on export-excel to do this which cause problems when adding data to an existing sheet (#555)
• Added new command Add-ExcelDataValidation which will apply different data-validation rules to ranges of cells
• Changed the export behavior so that (1) attempts to convert to a number only apply if the the value was a string; (2) Nulls are no longer converted to an empty string (3) there is a specific check for URIs and not just text which is a valid URI. Using UNC names in hyperlinks remains problematic.
• Changed the behavior of AutoSize in export excel so it only applies to the exported columns. Previously if something was exported next to pre-existing data, AutoSize would resize the whole sheet, potentially undoing things which had been set on the earlier data. If anyone relied on this behavior they will need to explicitly tell the sheet to auto size with $sheet.cells.autofitColumns. (where $sheet points to the sheet, it might be $ExcelPackage.Workbook.Worksheets['Name'])
• In Compare-Worksheet,the Key for comparing the sheets can now be written as a hash table with an expression - it is used with a Group-Object command so if it is valid in Group-Object it should be accepted; this allows the creation of composite keys when data being compared doesn't have a column which uniquely identifies rows.
• In Set-ExcelRange , added a 'Locked' option equivalent to the checkbox on the Protection Tab of the format cells dialog box in Excel.
• Created a Set-WorksheetProtection function. This gives the same options the protection dialog in Excel but is 0.9 release at the moment.

New Example

• Added MutipleValidations.ps1. Culled from the tests.

What's new 5.4.4

• Fix issue when only a single property is piped into Export-Excel
• Fix issue in Copy-ExcelWorksheet, close the $Stream

What's new 5.4.3

• Added Remove-Worksheet: Removes one or more worksheets from one or more workbooks

What's new 5.4.2

• Added parameters -GroupDateRow and -GroupDatePart & -GroupNumericRow, -GroupNumericMin, -GroupNumericMax and -GroupNumericInterval

  to Add-PivotTable and New-PivotTableDefinition. The date ones gather dates of the same year and/or quarter and/or month and/or day etc.

  the number ones group numbers into bands, starting at Min, and going up steps specified by Interval. Added tests and help for these.

• Set-ExcelRow and Set-ExcelColumn now check that the worksheet name they passed exists in the workbook.

What's new 5.4.0

• Thank you to Conrad Agramont, Twitter: @AGramont for the AddMultiWorkSheet.ps1 example. Much appreciated!
• Fixed several more bugs where parameters were ignored if passed a zero value
• Fixed bug where chart series headers could not come form a cell reference (=Sheet1!Z10 now works as a header reference)
• Add-Chart will now allow a single X range, or as many X ranges as there are Y ranges.
• Merge-MultipleSheets is more robust.
• Set-ExcelRow and Set-ExcelColumn trap attempts to process a sheet with no rows/columns.
• Help has been proof-read (thanks to Mrs. @Jhoneill !).

What's new 5.3.4

• HotFix for parameter PivotTableStyle should be PivotTableStyle https://github.com/dfinke/ImportExcel/issues/453

What's new 5.3.3

• Thank you to (lazywinadmin)[https://github.com/lazywinadmin] - Expand aliases in examples and elsewhere
• In Export-Excel fixed a bug where -AutoNameRange on pre-existing data included the header in the range.
• In Export-Excel fixed a bug which caused a zero, null, or empty string in a list of simple objects to be skipped.
• In Export-Excel improved the behaviour when a new worksheet is created without data, and Tables etc are added to it.
• In Join-Worksheet: added argument completer to -TitleBackgroundColor and set default for -TitleBackgroundStyle to 'Solid'.
• In Add-Excel chart, New-ExcelChart, tests and Examples fixed mis-spelling of "Position"
• In Send-SqlDataToExcel: improved robustness of check for no data returned.
• In Set-ExcelColumn: -column can come from the pipeline (supporting an array introduces complications for supporting script blocks); -AutoNameRange no longer requires heading to specified (so you can do 1..10 | Set-ExcelColumn -AutoNameRange ); In Set-ExcelRow: -Row can come from the pipeline
• Improved test coverage (back over 80%).
• Help and example improvements. In "Index - music.ps1" the module for querying the index can be downloaded from PowerShell gallery #requires set to demand it. In SQL+FillColumns+Pivot\example2.ps1 the GetSQL module can be downloaded and #Requires has been set. The F1 results spreadsheet is available from one drive and a link is provided.
• Added Azure DevOps continuous integration and badges

What's new in Release 5.3

• Help improvements and tidying up of examples and extra examples
• Open-Excel Package and Add-Worksheet now add worksheets as script properties so $Excel = Open-ExcelPackage -path test.xlsx ; $excel.sheet1 will return the sheet named "sheet1" $Excel.SheetName is a script property which is defined as $this.workbook.worksheets["Sheetname"]
• Renamed Set-Column to Set-ExcelColumn, Set-Row to Set-ExcelRow, and Set-Format, to Set-ExcelRange. Added aliases so the old names still work.
• Set-ExcelRange (or set-Format) used "Address" and "Range" incorrectly. There is now a single parameter -Range, with an alias of "Address". If the worksheet parameter is present, the function accepts a string specifying cells ("A1:Z10") or a the name of range. Without the worksheet it accepts an object representing a named range or a Table; or a tables's address, or part of the worksheet.cells collection.
• Add-ConditionalFormatting: Used "address" correctly, and it will accept ranges in the address parameter (range is now an alias for address). It now wraps conditional value strings in quotes when needed (for = <= >= operations string needs to be in double quotes see issue #424). Parameter intellisense has been improved. There are new parameters: -StopIfTrue and -Priority and support for using the -Reverse parameter with Color-scale rules (issue #430). Booleans in the sheet are now supported as the value for a condition. Also brought the two different kinds of condition together inside Export-Excel, and fixed a bug where named-ranges didn't work in some places. In New-ConditionalText, more types of conditional format are supported, and the argument completer for -ConditionalTextColor was missing and has been added.
• Improved handling of hyperlinks in Export-Excel (see issue #426)s
• Export-Excel has better checking of Table and PivotTable names (for uniqueness) and a new test in quick charts that there is suitable data for charting. It also accepts hash tables for chart, pivot table and conditional formatting parameters which are splatted into the functions which add these.
• Moved logic for adding a named-range out of Export-Excel and into a new function named Add-ExcelName, and logic for adding a table into a function named Add-ExcelTable; this is to make it easier to do these things independently of Export-Excel, but minimize duplication. The Add-ExcelTable command has extra parameters to toggle the options from table tools toolbar (show totals etc.) and set options in the totals row.
• Moved PivotTable Functions out of Export-Excel.PS1 into their own file and moved Add-ExcelChart out of Export-Excel.ps1 into New-ExcelChart.ps1
• Fixed bug in Merge-MultipleSheets where background pattern was set to None, making background color invisible.
• Fixed issues where formatting could be reset when using Export-Excel to manipulate an existing sheet without appending data; this applied to number-formats and tables.
• Add-PivotTable has some new parameters -PassThru returns the pivot table (e.g. to allow names /sort orders of data series to be tweaked ) -Address allows Pivot to be placed on an existing sheet; -PivotTableStyle allows a change from "Medium6", -PivotNumberFormat formats data cells. It is more flexible about how the source data is specified - copying the range options in Set-ExcelRange. Add-ExcelChart is now used for creating PivotCharts, and -PivotChartDefinition allows a definition created with New-ExcelChartDefinition to be used when setting up a PivotTable. This opens up all the things that Add-ExcelChart can do without duplicating the parameters on Add-Pivot table and Export-Excel. Definition, TableStyle, Numberformat and ChartDefiniton can be used in New-PivotTableDefinition .
• Add-ExcelChart now supports -PassThru to return the chart for tweaking after creation; there is now a -PivotTable parameter to allow Add-PivotTable to call the code in Add-ExcelChart. And in New-ExcelChartDefinition Legend parameters (for size, bold & position ) are now supported
• ChartDefinition and conditional formatting parameters can now be hashtables - anything that splats Add-ExcelChart or Add-ConditionalFormatting, it should be acceptable as a definition.

What's new in Release 5.2

• Value does not need to be mandatory in Set-Row or Set-Column, also tidied their parameters a little.
• Added support for array formulas in Set-Format (it really should be set range now that it sets values, formulas and hyperlinks - that can go on the to-do list )
• Fixed a bug with -Append in Export-Excel which caused it to overwrite the last row if the new data was a simple type.
• NumberFormat in Export-Excel now sets the default for on a new / blank sheet; but [still] sets individual cells when adding to a sheet
• Added support for timespans in Export excel ; set as elapsed hours, mins, secs [h]:mm:sss
• In Export-Excel improved the catch-all handler for insuring values to cope better with nested objects (#419) and reduce the number of parse operations
• Added -Calculate switch to Export-Excel and Close-Excel Package; EPPlus needs formulas to OMIT the leading = sign so where formula is set it now strips a leading = sign
• Added -PivotTotals parameter where there was already -NoTotalsInPivot new one allows None, Both, Rows, Columns. (#415)
• When appending Export-Excel only extended tables and ranges if they were explicitly specified. It now does it automatically.
• Compare and Merge worksheet originally had a problem with > 26 columns, I fixed merge turns out I hadn't fixed compare ... I have now
• Fixed bug where Export-Excel would not recognize it had to set $TitleFillPattern - made the default 'Solid'
• ExcludeProperty in Export-Excel now supports wildcards.
• Added DateTime to the list of types which can be exported as single column.
• Added Password support to Open- and Close-ExcelPackage (password was not doing anything in Export-Excel)
• Gave Expand-NumberFormat a better grasp of currency layouts - it follows .NET which is not always the same as Excel would set:-(

What's new in Release 5.1.1

• Set-Row and Set-Column will now create hyperlinks and insert dates correctly
• Import-Excel now has an argument completer for Worksheet name - this can be slow on large files
• The NumberFormat parameter (in Export-Excel, Set-Row, Set-Column, Set-Format and Add-ConditionalFormat) and X&YAxisNumberFormat parameters (in New-ExcelChartDefinition and Add-ExcelChart) now have an argument completer and the names Currency, Number, Percentage, Scientific, Fraction, Short Date ,Short time,Long time, Date-Time and Text will be converted to the correct Excel formatting strings.
• Added new function Select-Worksheet to make a named sheet active: Added -Activate switch to Add-Worksheet, to make current sheet active, Export-Excel and Add-PivotTable support -Activate and pass it to Add-Worksheet, and New-PivotTableDefinition allows it to be part of the Pivot TableDefinition.
• Fixed a bug in Set-Format which caused -Hidden not to work
• Made the same changes to Add-Conditional format as set format so -switch:$false is processed, and 0 enums and values are processed correctly
• In Export-Excel, wrapped calls to Add-CellValue in a try catch so a value which causes an issue doesn't crash the whole export but generates a warning instead (#410) .
• Additional tests.

What's new to July 18

• Changed parameter evaluation in Set-Format to support -bold:$false (and other switches so that if false is specified the attribute will be removed ), and to bug were enums with a value of zero, and other zero parameters were not set.
• Moved chart creation into its own function (Add-Excel chart) within Export-Excel.ps1. Renamed New-Excelchart to New-ExcelChartDefinition to make it clearer that it is not making anything in the workbook (but for compatibility put an alias of New-ExcelChart in so existing code does not break). Found that -Header does nothing, so it isn't Add-Excel chart and there is a message that does nothing in New-ExcelChartDefinition .
• Added -BarChart -ColumnChart -LineChart -PieChart parameters to Export-Excel for quick charts without giving a full chart definition.
• Added parameters for managing chart Axes and legend
• Added some chart tests to Export-Excel.tests.ps1. (but tests & examples for quick charts , axes or legends still on the to do list )
• Fixed some bad code which had been checked-in in-error and caused adding charts to break. (This was not seen outside GitHub #377)
• Added "Reverse" parameter to Add-ConditionalFormatting ; and added -PassThru to make it easier to modify details of conditional formatting rules after creation (#396)
• Refactored ConditionalFormatting code in Export excel to use Add-ConditionalFormatting.
• Rewrote Copy-ExcelWorksheet to use copy functionality rather than import | export (395)
• Found sorts could be inconsistent in Merge-MultipleWorksheet, so now sort on more columns.
• Fixed a bug introduced into Compare-Worksheet by the change described in the June changes below, this meant the font color was only being set in one sheet, when a row was changed. Also found that the PowerShell ISE and shell return Compare-Object results in different sequences which broke some tests. Applied a sort to ensure things are in a predictable order. (#375)
• Removed (2) calls to Get-ExcelColumnName (Removed and then restored function itself)
• Fixed an issue in Export-Excel where formulas were inserted as strings if "NoNumberConversion" is applied (#374), and made sure formatting is applied to formula cells
• Fixed an issue with parameter sets in Export-Excel not being determined correctly in some cases (I think this had been resolved before and might have regressed)
• Reverted the [double]::tryParse in export excel to the previous (longer) way, as the shorter way was not behaving correctly with with the number formats in certain regions. (also #374)
• Changed Table, Range and AutoRangeNames to apply to whole data area if no data has been inserted OR to inserted data only if it has.(#376) This means that if there are multiple inserts only inserted data is touched, rather than going as far down and/or right as the furthest used cell. Added a test for this.
• Added more of the Parameters from Export-Excel to Join-worksheet, join just calls export-excel with these parameters so there is no code behind them (#383)
• Added more of the Parameters from Export-Excel to Send-SQLDataToExcel, send just calls export-excel with these parameters...
• Added support for passing a System.Data.DataTable directly to Send-SQLDataToExcel
• Fixed a bug in Merge-MultipleSheets where if the key was "name", columns like "displayName" would not be processed correctly, nor would names like "something_ROW". Added tests for Compare, Merge and Join Worksheet
• Add-Worksheet , fixed a regression with move-after (#392), changed way default worksheet name is decided, so if none is specified, and an existing worksheet is copied (see June additions) and the name doesn't already exist, the original sheet name will be kept. (#393) If no name is given an a blank sheet is created, then it will be named sheetX where X is the number of the sheet (so if you have sheets FOO and BAR the new sheet will be Sheet3).

New in June 18

• New commands - Diff , Merge and Join

  • Compare-Worksheet (introduced in 5.0) uses the built in Compare-object command, to output a command-line DIFF and/or color the worksheet to show differences. For example, if my sheets are Windows services the extra rows or rows where the startup status has changed get highlighted

  • Merge-Worksheet (also introduced in 5.0) joins two lumps, side by highlighting the differences. So now I can have server A's services and Server Bs Services on the same page. I figured out a way to do multiple sheets. So I can have Server A,B,C,D on one page :-) that is Merge-MultpleSheets

    For this release I've fixed heaven only knows how many typos and proof reading errors in the help for these two, the only code change is to fix a bug if two worksheets have different names, are in different files and the Comparison sends the delta in the second back before the one in first, then highlighting changed properties could throw an error. Correcting the spelling of Merge-MultipleSheets is potentially a breaking change (and it is still plural!)

    also fixed a bug in compare worksheet where color might not be applied correctly when the worksheets came from different files and had different name.

  • Join-Worksheet is new for this release. At it's simplest it copies all the data in Worksheet A to the end of Worksheet B

• Add-Worksheet
  • I have moved this from ImportExcel.psm1 to ExportExcel.ps1 and it now can move a new worksheet to the right place, and can copy an existing worksheet (from the same or a different workbook) to a new one, and I set the Set return-type to aid intellisense
• New-PivotTableDefinition
  • Now Supports -PivotFilter and -PivotDataToColumn, -ChartHeight/width -ChartRow/Column, -ChartRow/ColumnPixelOffset parameters
• Set-Format
  • Fixed a bug where the -address parameter had to be named, although the examples in export-excel help showed it working by position (which works now. )
• Export-Excel
  • I've done some re-factoring
    1. I "flattened out" small "called-once" functions , add-title, convert-toNumber and Stop-ExcelProcess.
    2. It now uses Add-Worksheet, Open-ExcelPackage and Add-ConditionalFormat instead of duplicating their functionality.
    3. I've moved the PivotTable functionality (which was doubled up) out to a new function "Add-PivotTable" which supports some extra parameters PivotFilter and PivotDataToColumn, ChartHeight/width ChartRow/Column, ChartRow/ColumnPixelOffsets.
    4. I've made the try{} catch{} blocks cover smaller blocks of code to give a better idea where a failure happened, some of these now Warn instead of throwing - I'd rather save the data with warnings than throw it away because we can't add a chart. Along with this I've added some extra write-verbose messages
  • Bad column-names specified for Pivots now generate warnings instead of throwing.
  • Fixed issues when pivot tables / charts already exist and an export tries to create them again.
  • Fixed issue where AutoNamedRange, NamedRange, and TableName do not work when appending to a sheet which already contains the range(s) / table
  • Fixed issue where AutoNamedRange may try to create ranges with an illegal name.
  • Added check for illegal characters in RangeName or Table Name (replace them with "_"), changed tablename validation to allow spaces and applied same validation to RangeName
  • Fixed a bug where BoldTopRow is always bolds row 1 even if the export is told to start at a lower row.
  • Fixed a bug where titles throw pivot table creation out of alignment.
  • Fixed a bug where Append can overwrite the last rows of data if the initial export had blank rows at the top of the sheet.
  • Removed the need to specify a fill type when specifying a title background color
  • Added MoveToStart, MoveToEnd, MoveBefore and MoveAfter Parameters - these go straight through to Add worksheet
  • Added "NoScriptOrAliasProperties" "DisplayPropertySet" switches (names subject to change) - combined with ExcludeProperty these are a quick way to reduce the data exported (and speed things up)
  • Added PivotTableName Switch (in line with 5.0.1 release)
  • Add-CellValue now understands URI item properties. If a property is of type URI it is created as a hyperlink to speed up Add-CellValue
    • Commented out the write verbose statements even if verbose is silenced they cause a significant performance impact and if it's on they will cause a flood of messages.
    • Re-ordered the choices in the switch and added an option to say "If it is numeric already post it as is"
    • Added an option to only set the number format if doesn't match the default for the sheet.
• Export-Excel Pester Tests
  • I have converted examples 1-9, 11 and 13 from Export-Excel help into tests and have added some additional tests, and extra parameters to the example command to get better test coverage. The test so far has 184 "should" conditions grouped as 58 "IT" statements; but is still a work in progress.
• Compare-Worksheet pester tests
• James O'Neill added Compare-Worksheet
  • Compares two worksheets with the same name in different files.

4/22/2018

Thanks to the community yet again

• ili101 for fixes and features
  • Removed [PSPlot] as OutputType. Fixes it throwing an error
• Nasir Zubair added ConvertEmptyStringsToNull to the function ConvertFrom-ExcelToSQLInsert
  • If specified, cells without any data are replaced with NULL, instead of an empty string. This is to address behaviors in certain DBMS where an empty string is insert as 0 for INT column, instead of a NULL value.

4/10/2018

-New parameter -ReZip. It ReZips the xlsx so it can be imported to PowerBI

Thanks to Justin Grote for finding and fixing the error that Excel files created do not import to PowerBI online. Plus, thank you to CrashM for confirming the fix.

11/23/2017

More great additions and thanks to James O'Neill

• Added Convert-XlRangeToImage Gets the specified part of an Excel file and exports it as an image
• Fixed a typo in the message at line 373.

• Fixed some issues when appending to sheets where the header isn't in row 1 or the data doesn't start in column 1.
• Added support for more settings when creating a pivot chart.
• Corrected a typo PivotTableName was PivtoTableName in definition of New-PivotTableDefinition
• Add-ConditionalFormat and Set-Format added to the parameters so each has the choice of working more like the other.
• Added Set-Row and Set-Column - fill a formula down or across.
• Added Send-SQLDataToExcel. Insert a rowset and then call Export-Excel for ranges, charts, pivots etc.

10/30/2017

Huge thanks to James O'Neill. PowerShell aficionado. He always brings a flare when working with PowerShell. This is no exception.

(Check out the examples help Export-Excel -Examples)

• New parameter Package allows an ExcelPackage object returned by -passThru to be passed in
• New parameter ExcludeProperty to remove unwanted properties without needing to go through select-object
• New parameter Append code to read the existing headers and move the insertion point below the current data
• New parameter ClearSheet which removes the worksheet and any past data
• Remove any existing Pivot table before trying to [re]create it
• Check for inserting a pivot table so if -InsertPivotChart is specified it implies -InsertPivotTable

(Check out the examples help Export-Excel -Examples)

• New function Export-Charts (requires Excel to be installed) - Export Excel charts out as JPG files
• New function Add-ConditionalFormatting Adds conditional formatting to worksheet
• New function Set-Format Applies Number, font, alignment and color formatting to a range of Excel Cells
• ColorCompletion an argument completer for Colors for params across functions

I also worked out the parameters so you can do this, which is the same as passing -Now. It creates an Excel file name for you, does an auto fit and sets up filters.

ps | select Company, Handles | Export-Excel

10/13/2017

Added New-PivotTableDefinition. You can create and wire up a PivotTable to a WorkSheet. You can also create as many PivotTable Worksheets to point a one Worksheet. Or, you create many Worksheets and many corresponding PivotTable Worksheets.

Here you can create a WorkSheet with the data from Get-Service. Then create four PivotTables, pointing to the data each pivoting on a different dimension and showing a different chart

$base = @{
    SourceWorkSheet   = 'gsv'
    PivotData         = @{'Status' = 'count'}
    IncludePivotChart = $true
}

$ptd = [ordered]@{}

$ptd += New-PivotTableDefinition @base servicetype -PivotRows servicetype -ChartType Area3D
$ptd += New-PivotTableDefinition @base status -PivotRows status -ChartType PieExploded3D
$ptd += New-PivotTableDefinition @base starttype -PivotRows starttype -ChartType BarClustered3D
$ptd += New-PivotTableDefinition @base canstop -PivotRows canstop -ChartType ConeColStacked

Get-Service | Export-Excel -path $file -WorkSheetname gsv -Show -PivotTableDefinition $ptd

10/4/2017

Thanks to https://github.com/ili101 :

• Fix Bug, Unable to find type [PSPlot]
• Fix Bug, AutoFilter with TableName create corrupted Excel file.

10/2/2017

Thanks to Jeremy Brun Fixed issues related to use of -Title parameter combined with column formatting parameters.

• Issue #182
• Issue #89

9/28/2017 (Version 4.0.1)

• Added a new parameter called Password to import password protected files

• Added even more Pester tests for a more robust and bug free module

• Renamed parameter 'TopRow' to 'StartRow'

  This allows us to be more concise when new parameters ('StartColumn', ..) will be added in the future Your code will not break after the update, because we added an alias for backward compatibility

Special thanks to robinmalik for providing us with the code to implement this new feature. A high five to DarkLite1 for the implementation.

9/12/2017 (Version 4.0.0)

Super thanks and hat tip to DarkLite1. There is now a new and improved Import-Excel, not only in functionality, but also improved readability, examples and more. Not only that, he's been running it in production in his company for a number of weeks!

Added Update-FirstObjectProperties Updates the first object to contain all the properties of the object with the most properties in the array. Check out the help.

Breaking Changes: Due to a big portion of the code that is rewritten some slightly different behavior can be expected from the Import-Excel function. This is especially true for importing empty Excel files with or without using the TopRow parameter. To make sure that your code is still valid, please check the examples in the help or the accompanying Pester test file.

Moving forward, we are planning to include automatic testing with the help of Pester, Appveyor and Travis. From now on any changes in the module will have to be accompanied by the corresponding Pester tests to avoid breakages of code and functionality. This is in preparation for new features coming down the road.

7/3/2017

Thanks to Mikkel Nordberg. He contributed a ConvertTo-ExcelXlsx. To use it, Excel needs to be installed. The function converts the older Excel file format ending in .xls to the new format ending in .xlsx.

6/15/2017

Huge thank you to DarkLite1! Refactoring of code, adding help, adding features, fixing bugs. Specifically this long outstanding one:

Export-Excel: Numeric values not correct

It is fantastic to work with people like DarkLite1 in the community, to help make the module so much better. A hat to you.

Another shout out to Damian Reeves! His questions turn into great features. He asked if it was possible to import an Excel worksheet and transform the data into SQL INSERT statements. We can now answer that question with a big YES!

ConvertFrom-ExcelToSQLInsert People .\testSQLGen.xlsx

INSERT INTO People ('First', 'Last', 'The Zip') Values('John', 'Doe', '12345');
INSERT INTO People ('First', 'Last', 'The Zip') Values('Jim', 'Doe', '12345');
INSERT INTO People ('First', 'Last', 'The Zip') Values('Tom', 'Doe', '12345');
INSERT INTO People ('First', 'Last', 'The Zip') Values('Harry', 'Doe', '12345');
INSERT INTO People ('First', 'Last', 'The Zip') Values('Jane', 'Doe', '12345');

Bonus Points

Use the underlying ConvertFrom-ExcelData function and you can use a scriptblock to format the data however you want.

ConvertFrom-ExcelData .\testSQLGen.xlsx {
    param($propertyNames, $record)

    $reportRecord = @()
    foreach ($pn in $propertyNames) {
        $reportRecord += "{0}: {1}" -f $pn, $record.$pn
    }
    $reportRecord +=""
    $reportRecord -join "`r`n"
}

Generates

First: John
Last: Doe
The Zip: 12345

First: Jim
Last: Doe
The Zip: 12345

First: Tom
Last: Doe
The Zip: 12345

First: Harry
Last: Doe
The Zip: 12345

First: Jane
Last: Doe
The Zip: 12345

Thank you to DarkLite1 for more updates

• TableName with parameter validation, throws an error when the TableName:
  • Starts with something else then a letter
  • Is NULL or empty
  • Contains spaces
• Numeric parsing now uses CurrentInfo to use the system settings

2/14/2017

Big thanks to DarkLite1 for some great updates

• -DataOnly switch added to Import-Excel. When used it will only generate objects for rows that contain text values, not for empty rows or columns.

        )

        Set-CellStyle $workSheet 1 $LastColumn Solid Cyan

        foreach($row in (2..$totalRows | Where-Object {$_ % 2 -eq 0})) {
            Set-CellStyle $workSheet $row $LastColumn Solid Gray
        }

        foreach($row in (2..$totalRows | Where-Object {$_ % 2 -eq 1})) {
            Set-CellStyle $workSheet $row $LastColumn Solid LightGray
        }
    }

9/28/2016

Fixed PowerShell 3.0 compatibility. Thanks to headsphere. He used $obj.PSObject.Methods[$target] syntax to make it backward compatible. PS v4.0 and later allow $obj.$target.

Thank you to xelsirko for fixing - Import-module importexcel gives version warning if started inside background job

8/12/2016

Fixed reading the headers from cells, moved from using Text property to Value property.

4/30/2016

Huge thank you to Willie Möller

• He added a version check so the PowerShell Classes don't cause issues for down-level version of PowerShell
• He also contributed the first Pester tests for the module. Super! Check them out, they'll be the way tests will be implemented going forward

4/18/2016

Thanks to Paul Williams for this feature. Now data can be transposed to columns for better charting.

10/20/2015

Big bug fix for version 3.0 PowerShell folks!

This technique fails in 3.0 and works in 4.0 and later.

$m="substring"
"hello".$m(2,1)

Adding .invoke works in 3.0 and later.

$m="substring"
"hello".$m.invoke(2,1)

A big thank you to DarkLite1 for adding the help to Export-Excel.

Added -HeaderRow parameter. Sometimes the heading does not start in Row 1.

10/16/2015

Fixes Export-Excel generates corrupt Excel file

10/15/2015

Import-Excel has a new parameter NoHeader. If data in the sheet does not have headers and you don't want to supply your own, Import-Excel will generate the property name.

Import-Excel now returns .Value rather than .Text

10/1/2015

Merged ValidateSet for Encoding and Extension. Thank you Irwin Strachan.

9/30/2015

Export-Excel can now handle data that is not an object

echo a b c 1 $true 2.1 1/1/2015 | Export-Excel c:\temp\test.xlsx -Show

Or

dir -Name | Export-Excel c:\temp\test.xlsx -Show

9/25/2015

Hide worksheets Got a great request from forensicsguy20012004 to hide worksheets. You create a few pivotables, generate charts and then pivot table worksheets don't need to be visible.

Export-Excel now has a -HideSheet parameter that takes and array of worksheet names and hides them.

Example

Here, you create four worksheets named PM,Handles,Services and Files.

The last line creates the Files sheet and then hides the Handles,Services sheets.

$p = Get-Process

$p|select company, pm | Export-Excel $xlFile -WorkSheetname PM
$p|select company, handles| Export-Excel $xlFile -WorkSheetname Handles
Get-Service| Export-Excel $xlFile -WorkSheetname Services

dir -File | Export-Excel $xlFile -WorkSheetname Files -Show -HideSheet Handles, Services

Note There is a bug in EPPlus that does not let you hide the first worksheet created. Hopefully it'll resolved soon.

9/11/2015

Added Conditional formatting. See TryConditional.ps1 as an example.

Or, check out the short "How To" video.

8/21/2015

• Now import Excel sheets even if the file is open in Excel. Thank you Francois Lachance-Guillemette

7/09/2015

• For -PivotRows you can pass a hashtable with the name of the property and the type of calculation. Sum, Average, Max, Min, Product, StdDev, StdDevp, Var, Varp

Get-Service |
    Export-Excel "c:\temp\test.xlsx" `
        -Show `
        -IncludePivotTable `
        -PivotRows status `
        -PivotData @{status='count'}

6/16/2015 (Thanks Justin)

• Improvements to PivotTable overwriting
• Added two parameters to Export-Excel
  • RangeName - Turns the data piped to Export-Excel into a named range.
  • TableName - Turns the data piped to Export-Excel into an excel table.

Examples

Get-Process|Export-Excel foo.xlsx -Verbose -IncludePivotTable -TableName "Processes" -Show
Get-Process|Export-Excel foo.xlsx -Verbose -IncludePivotTable -RangeName "Processes" -Show

5/25/2015

• Fixed null header problem

5/17/2015

• Added three parameters:
  • FreezeTopRow - Freezes the first row of the data
  • AutoFilter - Enables filtering for the data in the sheet
  • BoldTopRow - Bolds the top row of data, the column headers

Example

Get-CimInstance win32_service |
    select state, accept*, start*, caption |
    Export-Excel test.xlsx -Show -BoldTopRow -AutoFilter -FreezeTopRow -AutoSize

5/4/2015

• Published to PowerShell Gallery. In PowerShell v5 use Find-Module importexcel then Find-Module importexcel | Install-Module

4/27/2015

• datetime properties were displaying as ints, now are formatted

4/25/2015

• Now you can create multiple Pivot tables in one pass
  • Thanks to pscookiemonster, he submitted a repro case to the EPPlus CodePlex project and got it fixed

Example

$ps = ps

$ps |
    Export-Excel .\testExport.xlsx  -WorkSheetname memory `
        -IncludePivotTable -PivotRows Company -PivotData PM `
        -IncludePivotChart -ChartType PieExploded3D
$ps |
    Export-Excel .\testExport.xlsx  -WorkSheetname handles `
        -IncludePivotTable -PivotRows Company -PivotData Handles `
        -IncludePivotChart -ChartType PieExploded3D -Show

4/20/2015

• Included and embellished Claus Nielsen function to take all sheets in an Excel file workbook and create a text file for each ConvertFrom-ExcelSheet
• Renamed Export-MultipleExcelSheets to ConvertFrom-ExcelSheet

4/13/2015

• You can add a title to the Excel "Report" Title, TitleFillPattern, TitleBold, TitleSize, TitleBackgroundColor
  • Thanks to Irwin Strachan for this and other great suggestions, testing and more

4/10/2015

• Renamed AutoFitColumns to AutoSize
• Implemented Export-MultipleExcelSheets
• Implemented -Password for a worksheet
• Replaced -Force switch with -NoClobber switch
• Added examples for Get-Help
• If Pivot table is requested, that sheet becomes the tab selected

4/8/2015

• Implemented exporting data to named sheets via the -WorkSheetname parameter.

Examples - gsv | Export-Excel .\test.xlsx -WorkSheetname Services

dir -file | Export-Excel .\test.xlsx -WorkSheetname Files

ps | Export-Excel .\test.xlsx -WorkSheetname Processes -IncludePivotTable -Show -PivotRows Company -PivotData PM

Convert (All or Some) Excel Sheets to Text files

Reads each sheet in TestSheets.xlsx and outputs it to the data directory as the sheet name with the extension .txt

ConvertFrom-ExcelSheet .\TestSheets.xlsx .\data

Reads and outputs sheets like Sheet10 and Sheet20 form TestSheets.xlsx and outputs it to the data directory as the sheet name with the extension .txt

ConvertFrom-ExcelSheet .\TestSheets.xlsx .\data sheet?0

Example Adding a Title

You can set the pattern, size and of if the title is bold.

$p=@{
    Title = "Process Report as of $(Get-Date)"
    TitleFillPattern = "LightTrellis"
    TitleSize = 18
    TitleBold = $true

    Path  = "$pwd\testExport.xlsx"
    Show = $true
    AutoSize = $true
}

Get-Process |
    Where Company | Select Company, PM |
    Export-Excel @p

Example Export-MultipleExcelSheets

$p = Get-Process

$DataToGather = @{
    PM        = {$p|select company, pm}
    Handles   = {$p|select company, handles}
    Services  = {gsv}
    Files     = {dir -File}
    Albums    = {(Invoke-RestMethod http://www.dougfinke.com/PowerShellfordevelopers/albums.js)}
}

Export-MultipleExcelSheets -Show -AutoSize .\testExport.xlsx $DataToGather

NOTE If the sheet exists when using -WorkSheetname parameter, it will be deleted and then added with the new data.

You can also find EPPLus on Nuget.

Known Issues

• Using -IncludePivotTable, if that pivot table name exists, you'll get an error.
  • Investigating a solution
  • Workaround delete the Excel file first, then do the export
