I just finished my project with Studio 2008, Excel 2007, and C#. I read a csv
file, parse the data, and enter it into a formatted excel spreadsheet.

I just learned that it's going to need to be functional for all versions of
excel after 97, however.

I Wrote it specifically for 2007.

How would any of you recommend doing this?

I have the code written, but I doubt it's going to work on previous versions..

Right now i'm using the Excel 12.0 object library. Is there a library that
will handle multiple versions?

The reason is that my client base may have anywhere from excel 97 to 2007
installed, and there is a wide group.

Any help would be greatly appreciated.
