It is powerful! Thanks.

I had been looking for a good library that reads / writes XLS files for a long time, and finally found NPOI. Great job, the API is simple and efficient. It took me one hour tops to convert from the old Excel automation to NPOI, and now we can finally manipulate spreadsheets on the server. You should definitely advertise more, because I wouldn't have found NPOI if it hadn't been for Leniel's blog.
