Realistic seed data on demand.
Tip: use samples, upload, copy, download, and send-to actions inside the workspace where available.
Fake Dataset Generator is a free, browser-based tool that helps you produce ready-to-use output in seconds. Realistic seed data on demand. It's built for speed and privacy: Everything runs locally in your browser — your data is never uploaded to a server. No sign-up, no installs, and no daily limits.
Generate a sample or helper artifact, then copy it into the workflow that needs it.
Review the preview, copy or download the result, and keep everything local in your browser.
Auto Schema Detector: Infer a schema (types, nullability, uniqueness) from any sample dataset.
