C# converting .xls to .csv without Excel [duplicate]

Question

Need to convert a .xls or .xlsx to a .csv without the use of Excel in an C#/ASP.net web app. The application is currently using the NPOI.dll for some functionality but I do not see any info on the codeplex wiki for NPOI for that particular functionality. Does anyone have any suggestions?

Thanks

There are libraries ( Excel Data Reader, for eg) that let you read excel. Once you are able to read data, writing to csv should be simple.
