Myrna Larson and Bill Manville have developed a compare that's very nice.
http://www.cpearson.com/excel/whatsnew.htm
look for compare.xla
But the bad news is that this does a cell-by-cell comparison.
A1 compares to A1, x99 to x99, etc.
If you insert/delete a row or column, then this won't work very well.

Another alternative that may work depending on what kind of differences you're
looking for (values, not formulas, not formatting, not comments, not objects):
Save each worksheet as a .csv file and use any comparison program you want to
compare two text files--like MSWord.
