Your data never leaves your browser

  • Nothing is uploaded

    Files are read and cleaned on your own device. Customer emails, phones and CRM rows never reach our server: the tools have nothing to send them to.

  • Built on each platform's published rules

    Every format, header and hashing rule comes from the ad platform's own help pages, linked on each tool with the date we last checked it.

  • Free, no sign-up

    No email walls, no trials. Large files (100,000 rows and more) are processed in the background so the page never freezes.
