Hi Peter,
Here are the instructions for converting Works (version 4.5 incl) to XL 97.
Don't worry XL 97 is compatible with XL 2000. If you can open it in XL 97,
you will have now difficulty with XL 2000.
If you had some complicated macros, then there is a chance you might have
had difficulties of some sort. But given that you are using Works, I
suspect that you have data only.
