visual basic express read/write to excel question

It's pretty simple with the Microsoft Office Interop namespaces... http://msdn.microsoft.com/en-US/libr...=vs.80%29.aspx

Why are you using Excel though? Just to see if you can input the data to a spreadsheet? :S The calculation part of it can be done with functions in Excel directly.

If you don't want to do it the COM way, then you could attempt uncompressing the archive (compressed with the DEFLATE/Base64 method like most zip archives) to reveal all of the XML files that are used for the spreadsheet, and edit those.
