Hi,
I'm a a co-worker sending me spreadsheets that are created in alother
program and saved as Excel files. I have no problem opening these in MS
Excel 2003 or 2007, but I do get a message that says the file is in a
different format than specified by the file extension but it opens fine.

When I tyr to open these in MS Excel Viewer, it tells me the file is
corrupt. I don't need the full version of Excel with me on my notebook and
was hoping to just use the viewer. Is there a program from MS that can check
and correct these Excel files, like a recovery program, so I can use these
with viewer? Thanks.

Regards-Michael G.
