Let's say you have two Excel files, or maybe two versions of the same file, that you want to compare.
Or maybe you want to find potential problems, like manually-entered (instead of calculated) totals, or broken formulas.
This is one of the basic tasks if you are working with excel files.
If you have relatively small excel files, you can view files side-by-side to find all differences. But, for example, if
you are working with Price Lists, each one have 200 rows and 20 columns - the most likely you will miss something.
There are a lot of articles on the Internet on how to compare 2 files using VLOOKUP or other formulas. If you are doing this on
the daily basis - there is no sense to spend time for this - let professionals to do this job for you!
