About this tool
JSON → CSV: a practical, privacy-safe guide
JSON ↔ CSV processes JSON right where you are. Paste your input, review any options, and copy the CSV output — no uploads, no account, no waiting on a server.
Document conversion matters whenever a file has to cross a boundary — when a client opens a different office suite, an upload form accepts only one format, or a report must print identically everywhere. Doing it in the browser removes the riskiest step: handing your document to an unknown server.
Privacy by construction: JSON ↔ CSV runs entirely in your device's memory. Your files, text and data are never uploaded, stored or logged by us — there is no server in the path.
100% in-browser — nothing is uploaded
No account or sign-up required
Free to use, no watermarks
