如何使用python 3从Excel中的宏单元格读取值

Question

我正在尝试使用 openpyxl 库从 python 中基于宏的 xls 文件（.xlsm）读取内容。我想从单元格中读取值，但我获取的是宏公式，而不是单元格中宏的填充值。 有什么方法可以从 python 中的单元格内容中获取值吗？

######## 下面是示例代码###########

import openpyxl

def generate_output_file(template_path, output_path):

    # Load/open the existing workbook template
    old_wb = openpyxl.load_workbook(template_path, keep_vba=True)
    old_sheet = old_wb['sheet1']

    # Sample logic for inserting data in sheet1 which will trigger macro and populate some values
    # in other cells(eg. C276) of sheet1
    old_sheet['B55'] = 'abcd'

    # Save the modified workbook
    old_wb.save(output_path)

    # Now open the modified file in same instance
    new_wb = openpyxl.load_workbook(output_path, data_only=True)
    new_sh = new_wb.get_sheet_by_name('sheet1')

    # this should show populated values of macro cell, but showing None
    print(new_sh['C276'].value)

if __name__ == "__main__":

    template_path = "C:\\macro_xls\\sample_test.xlsm"
    output_path = "C:\\macro_xls\\sample_test_output.xlsm"
    generate_output_file(template_path, output_path)

Answer 1

您可以设置

data_only=True

从带有公式的单元格中读取值。

from openpyxl import load_workbook
wb = load_workbook("yourData.xlsm", data_only=True)
ws = wb['test']
cell = ws['A1']
value = cell.value

来自doc：

data_only

(bool) – 控制带有公式的单元格是否具有 公式（默认）或上次 Excel 读取时存储的值 片
