Compare lists online

No install, no signup. Open this page, paste your lists, and compare. The work happens in your browser, so 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 exports 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.
