1.简介

文档： http://qtxlsx.debao.me

QtXlsx 是一个可以读取和写入 Excel 文件的库。它不需要 Microsoft Excel，可以在 Qt5 支持的任何平台上使用。该库可用于

从头开始生成新的 .xlsx 文件
从现有 .xlsx 文件中提取数据
编辑现有 .xlsx 文件

2.下载

从github download 源码：

GitHub - dbzhang800/QtXlsxWriter：Qt5 的 .xlsx 文件读取器和写入器https://github.com/dbzhang800/QtXlsxWriter/tree/master

3.编译与安装

下载完之后为一个压缩包：
解压压缩包后源码：
打开QtCreator，打开解压文件的 qtxlsx.pro 项目，如图所示：
按照自己需要构建项目：
等待编译完成后生成库文件：
复制库文件和头文件等到qt的安装目录：
把以上选择的文件夹复制到相应安装目录（注意编译时选择的编译器，要把编译后的库文件安装到对应的编译器版本目录）：

4.demo介绍

这里主要介绍 QtXlsxWriter-master\examples\xlsx\demo 目录下的demo代码，这个demo代码生成一个 Book1.xlsx 文件，这个文件示例包含经常使用的功能。
