Problem opening excel document?

All versions of Excel since 97 use the same file format, so no conversion is necessary. If you can't open the file, it is probably corrupt.

Sometimes I find that Open Office Calc is much more successful when attempting to open damaged Excel files than Excel itself - it might be worth downloading it (it's free, do a Google search) and giving it a try. Possibly, even if this works, you may not be able to recover all your data though (as .xls is not the OO program's native format).
