python中openpyxl和xlsxwriter对Excel的操作方法

时间：2022-10-14 08:04:43

前几天，项目中有个小需求：提供Excel的上传下载功能，使用模块：openpyxl 和 xlsxwriter，这里简单记录一下。

1.简介

Python中操作Excel的库非常多，为开发者提供了多种选择，如：xlrd、 xlwt、xlutils、xlwings、pandas、 win32com、openpyxl、xlsxwriter等等。
其中：

前三个一般混合使用，对Excel读写操作，适合旧版Excel，仅支持 xls 文件；

  • win32com 库功能丰富，性能强大，适用于Windows；
  • xlwings稍次于前者，但同样功能丰富；pandas适合处理大量数据；
  • xlsxwriter 适合大量数据的写操作，支持图片/表格/图表/筛选/格式/公式等；
  • openpyxl 读写均可，简单易用，功能广泛，可插入图表等，类似前者。

以下主要描述一下后两种（openpyxl、xlsxwriter）的简单使用
