How can I add new values to an uploaded application/vnd.ms-excel file in C#? Can anybody help?

If you're using Excel 2007/2010 you can make use of Microsoft's added XML standard with various third party libraries.

I've used EPPlus in the past, but its license dictates if you release your project to the public you must release its source as well.

For that reason I've used ClosedXML to manipulate excel files (.xlsx and .xlsm). You open workbooks from a disk location, or from a filestream.
