Small programs import Excel data in batches, and cloud development database exports CVS garbled code solution

When we import data into the applet cloud development database , use json It can perfectly avoid the problem of garbled code , But if it's a lot of data , Editing data is more troublesome , It doesn't look very beautiful . So the best way is excel Well edited , Then batch import into the applet database .

But what? , The data we import into the applet database only supports csv and json Formatted data .

If we want to import excel The data of , You have to put excel Convert to csv. In fact, this step is very simple

One , Import excel Data to applet database

First of all , We build a new one excel, Then write your own data . Here's the picture

Then start editing the data

1-1, matters needing attention

1, The first line is your field name in the database

2, The first 2 The beginning of the line is the real data

Because the data in our database has corresponding field names , So the field name should be placed on the first line , As shown in the red box below

Insert picture description here

1-2, edit excel data

As shown in the figure above , Suppose there are three fields in our commodity data table _id,name,price

The first row must be the field in the database , Preferably pinyin or English .

1-3, hold excel Convert to csv Format

Click on excel The file in the upper left corner

Then click Save as

When saving as, select the format CVS Of UTF-8( Comma separated )

So let's do that excel Convert to csv Format , Is it simple

1-4, Import csv To the cloud development database

It's edited csv Format data after , You can import it into the database

Choose the one from the previous step Programming little stone .csv

Then wait for the import to complete

The effect picture after import is as follows

Here we are excel The data can be successfully imported into the applet cloud development database .

Two , Applet exported csv Solve the problem of disorderly code

We can also directly export the data in the applet database to excel, But the same question is , Applet database export data can only be exported json perhaps csv.

Actually , Same principle , Let's export it as csv, And then convert it to excel That's all right.

2-1, Export set data to csv

But there's a problem , It's exported csv When , You must fill in the fields to export .

As shown here, I want to import the three fields in the red box in the figure above , Fill in as shown in the figure below . Remember to separate them with commas in English

The following figure shows the data we exported

But there is a problem after the data is opened

2-2, solve csv The code problem

As shown in the figure below , We exported it csv After data opening , There will be garbled Chinese .

This problem is easy to solve .

1, Right click the exported csv file , Open in Notepad

2, After Notepad is opened , Click on the file ---》 Save as

3, Change the encoding format to ANSI

Open it again and you can see that the garbled code problem has been solved

If you want to add data or modify data to the exported data , Remember to repeat the first step excel Convert to csv The steps of format are all right .

Here we can happily import excel To applet database and applet database export to excel 了 .

I think it's good. I can pay attention to brother stone , There will be more and better small program tutorials for you later .
