Three components of openpyxl

1. workbook

2. Worksheet

3. Cell

Read excel File data ：

def read_excel(path):
    #1. Get the workbooks 
    wk = openpyxl.load_workbook(path)

    # 2. Get worksheet 
    sheets = wk.sheetnames
    for sheet in sheets:
        my_sheet = wk[sheet]
        result = list()
        
        # 3. Get the cell 
        for row in range(2,my_sheet.max_row+1):
            result_row = list()
            for column in range(1,my_sheet.max_column+1):
                result_row.append(my_sheet.cell(row,column).value)
            result.append(result_row)
        print(result)

Write table data ：

def create_excel():
    #1. Create Workbook 
    wk = openpyxl.Workbook()
    #2. Get current worksheet 
    my_sheet = wk.active

    #3. Write data 
    my_sheet.cell(1,1).value = "name"
    my_sheet.cell(1,2).value = "age"

    #4. Save table 
    wk.save("user.xlsx")

Write multiple pieces of data ：

def add_manyuData(path):
    #1. Open workbook in total 
    wk = openpyxl.load_workbook(path)

    #2. Create sheet 
    my_sheet = wk.create_sheet()

    #3. Write data once 
    data = [1,2,3,4,5,6]
    my_sheet.append(data)

    #4. Save workbook 
    wk.save(path)
