List Intersection Difference
Find common and unique items in two lists.
Compare two lists
Paste two lists and this shows their intersection (in both), and each list's difference (only in one) — the set operations behind reconciling two exports or spotting what changed.
It is the fast reconciliation tool — which emails are on both lists, which are only in the new export, which dropped off — without writing a lookup formula.
Line by line
Each line is one item, compared as written. Your lists are compared on your device and never uploaded. Comparing last month's subscribers against this month's, for example, shows at a glance who joined, who left, and who stayed.
