I'm going to ask a couple questions here, for clarification.

• What Platform are you on?
• How many files are there?

If you're on Win32, try Win32::OLE...for the challenge, if nothing else *grin*.

Otherwise the two Spreadsheet:: modules listed above will help greatly. (I'm also going to take this opportunity to suggest that you take a look at my Scratch Pad, where I've been putting together a bit of a FAQ/How-To regarding Win32::OLE and Excel - I'll post it under Tutorials when it's done, comments welcome).

If it's just one file, why automate? Go through each sheet, SaveAs CSV, append them together, and move on.
