步骤：

安装microsoft的excel软件，因为只有ms的excel软件才提供了有关的类库
选中工程，添加类→MFC→Typelib中的MFC类
选中类库，在可用类类型库中选择Microsoft Excel Object Library(据版本有可能细微之不同)
添加需要使用的接口，根据网上大部分人的说法和能满足我需要的类就只有5个类CApplication, CWorkBook, CWorkSheet, CWorkBooks, CWorkSheets, CRange，选择接口时分别是_Application, _WorkBook, _WorkSheet, Range, WorkBooks, WorkSheets，选择好后点确定，就会多5个头文件，删除每个头文件里面的开头的“#import “C:\Program Files (x86)\Microsoft Office\Office12\EXCEL.EXE” no_namespace”，不删除则会有莫名其妙编译错误文章来源地址https://www.toymoban.com/news/detail-602625.html
