使用python设置excel单元格格式为常规、日期、数字

使用openpyxl来设置Excel单元格的格式，总结如下：

一、导入：

from openpyxl.styles import numbers  或

import openpyxl

 

二、使用：

1、将单元格[2,3]，设置为 “常规” 格式

work_sheet.cell(row=2, column=3).number_format = 'General'

2、将单元格[2,3]，设置为 “纯文本” 格式

work_sheet.cell(row=2, column=3).number_format = '@'

3、将单元格[2,3]，设置为 “自定义” 格式中的“0”

work_sheet.cell(row=2, column=3).number_format = '0'

3、将单元格[2,3]，设置为 “自定义” 格式中的“0.000”

work_sheet.cell(row=2, column=3).number_format = '0.000'
