Question

I want to use npoi to manage .xlsx files in VS2012/2010 . To do this, I have to import NPOI.XSSF.UserModel , but when I add npoi.dll and try to import it, there is no NPOI type XSSF NPOI . I mean there is no " Using NPOI.XSSF " Any help?

You need to enable NPOI.OOXML.dll dll to use the NPOI.XSSF.UserModel namespace
