MS提供OpenXML SDK V 2.5 - 请参阅https://msdn.microsoft.com/en-us/library/bb448854(v=office.15).aspx
这可以读取+写入MS Office文件(包括Excel)...
另一个选项见http://www.codeproject.com/KB/office/OpenXML.aspx
如果您需要更多像渲染,公式等,那么有不同的商业库,如Aspose和Flexcel ......
您是否听说过 NPOI，这是一个无需安装 Microsoft Office 即可读取/写入 Office 格式的 .NET 库。没有 COM+，就没有互操作。GitHub页面
