If you wanted to look at a cell by cell comparison to compare two worksheets
cell by cell (A1 with A1, x99 with x99...), you could try this addin developed
by Myrna Larson and Bill Manville.

look for compare.xla

If you think that a row or column was added or deleted, this kind of comparison
soon loses its effectiveness.

Hi,
I have an excel file which is updated regularly and then a backup was made.
unfortunaltely the orginal as well as the backup have been updated. is there
a utility or formula etc. that I can compare the workboor or worksheets and
tell me which cells are different. I don't even need to know what the
differences are since I can do it manually, but that that would be nice.

Thanks,
