This project is the .NET version of POI Java project at http://poi.apache.org/. POI is an open source project which can help you read/write xls, doc, ppt files. It has a wide application. For example, you can use it to generate a Excel report without Microsoft Office suite installed on your server and more efficient than call Microsoft Excel ActiveX at background; you can also use it to extract text from Office documents to help you implement full-text indexing feature (most of time this feature is used to create search engines).

Someone may find that there is already a project called POI.NET by Johannes Roith, which is located at http://developer.novell.com/wiki/index.php/Poi.Net. However, this project is out of date. Some of the code are based on old version of POI, which may contain some bugs. Moreover, there is no source code available though you can use Reflector to view the source code.
