The Parkvara Sandbox makes synthetic data that has the same shape as yours but none of the real records — so you can experiment, learn and vibe-code without a single real value ever leaving your machine. One web page, zero dependencies, nothing to install.
Runs entirely on your device · synthetic data only · no upload, no account.
Drop in a CSV or Excel file and the Sandbox generates a synthetic copy with the same columns and patterns — and entirely made-up values.
Generation happens locally. Your real file is never uploaded, stored or sent anywhere.
Flags identifier fields and shows what's safe to keep — so you learn the data-safety habit while you work.
Synthetic practice data is low-risk, not legally anonymous. The Sandbox is built to teach that distinction, not paper over it.
Every Building-with-AI and Governance exercise runs on Sandbox data. Practise cleaning, analysing and checking figures — break things safely, learn fast, and never risk a real record.
