Just to add to Dick's response...

Rob Bovey has a utility that does the export/import for you (cleaning up the
code).

You can find it at:
http://www.appspro.com/


And if that doesn't help:

You may want to try OpenOffice. If the file is corrupted, OpenOffice may be
able to open it.

http://www.openoffice.org, a 60-65 meg download or a CD

And if the file is corrupted and is really important, there are commercial
recovery services. I've never used it, but you might want to check into:
http://www.officerecovery.com

I have developed an application in Excel 2000 (SP3) for a colleague using
2003. The main bulk of the application is moving data around, although there
is some charting.

When my colleague tries to open the workbook he gets the usual secuirty
warning about opening the book with the macros in and then gets an error
message saying that Excel has encountered a problem and has to close. If you
reopen it Excel tries to 'repair' the problem by removing the VBA.

Is this a compatibility issue?

Thanks,
Ben
