Why don't identical-looking emails match?
Case must currently match: Lin@example.com and lin@example.com count as different items. You can check the matching rules for case, extra spaces and hidden characters to adjust how items are compared.

A free browser-based tool to paste two lists and see what's only in one, what's in both, and which items almost match, with results you can copy or download.
The story so far
List Matcher lets you compare two lists or spreadsheets directly in your browser. Paste two lists or drop XLSX, XLS, ODS, CSV and TXT files to see what's only in one list, what appears in both, and identify items that look similar but didn't match according to your rules.
The tool processes everything in your browser tab without uploading your data. You can customize matching rules to ignore spaces, hidden characters, case differences, extra spacing, and leading zeros. Results can be viewed in different formats and copied or downloaded as TXT or CSV files.
Common uses include checking event attendance, removing unsubscribed addresses from mailing lists, verifying data migrations, and finding missing items in inventory or order fulfillment. You can save workflow settings on your device for repeated comparisons.

Questions and answers
Which row is kept when an email appears twice?
Within each list, the first row with that matching email is kept. If other columns differ, you can inspect the conflicting records.
How do I copy names and departments too?
Add the full tables, match by email, then choose full rows as the output. Check the column headers above the results before copying.
Can I compare 100,000 or a million lines?
Yes, you can try two generated lists on the device to test performance with large datasets.
