Your data never leaves your device.

Everything runs in your browser. Your projects live on your device.

  • Runs entirely in your browser. We don't upload or store your CSV files on our servers.
  • Projects are saved locally in your browser. Clearing site data or using Incognito will remove themβ€”export projects to back them up.
  • For very large files, split into smaller chunks or use streaming mode; we're building a Desktop app for heavy workflows.
β€œTransform in the tab. Export when you're ready.β€β€œYour browser, your data, your rules.β€β€œNo uploads. No cloud. No surprises.”
