• (操作Excel 2007以後)Open XML SDK 2.0 for Microsoft Office


    Office 2007後,

    是基於OPENXML來實現的,也就是說Office 2007都是用openxml來開發的。

     

    如果不用安裝open xml sdk也可以,你會操作xml文檔就可以了,open xml sdk只不過封裝了一些操作xml的方法

     

    因為office 2007文檔的本質就是xml文件,你把office 2007文檔的後綴名改為zip,然後解壓,你就會發現原來是一堆的xml文件而以

     

    2003及以下的文檔本質是二進制文檔,2007以後的都是xml文檔,

    不過生成的2007或之後的文檔在20002003都是可以打開的
