Compare two Excel files

How to compare two sales Excel files without drawing the wrong conclusion?

Comparing two sales exports is not just subtracting one from the other. You first need to know whether they cover two separate periods, the same scope, or whether file B already includes file A.

In short

This query usually comes from teams receiving two CRM, ERP or Excel exports and trying to understand what changed without building a full dashboard.
