Diff two CSV exports, visually

Comparing two exports of the same report line by line in a text diff is painful. Drop both CSV files (the original first) and they're compared value by value. The newer one opens in Mega Excel Studio with changed values filled amber, new values green and removed ones red, each with its old value in a note, plus a Differences sheet that lists every change. Download it as Excel, or export the Differences sheet as CSV.
