SafeSeed: In-Browser App

Build a test or demo CSV entirely from SafeSeed’s catalog, then download the exact CSV and its matching verification file.

No production file is accepted by the generator. No accounts, analytics, or network requests.

JavaScript is required to generate or verify

Enable JavaScript for this local tool, or use the SafeSeed command-line package. The page remains readable without scripts so the purpose and boundary are never hidden behind the app.

Not legal advice. SafeSeed is a technical control, not proof that a file contains no personal data.
