Compare lists online—no account
Want to compare lists online—or just compare a list against another without installing anything? Open this page, paste or upload, and run the compare in your browser. You don’t send the lists to us just to see the differences.
What that means in practice
- You don’t create an account to compare.
- You can paste text or upload TXT, CSV, or JSON.
- Results stay in the page until you copy or download them.

Good fit when…
- You’re checking two downloaded lists or spreadsheets against each other.
- You want to see the overlap before cleaning a sheet.
- You don’t want to install anything for a one-time job.
