Our mission

JSON is everywhere — API responses, config files, build pipelines, data exports. Yet most online tools for working with it upload your data to a remote server you don't control. MyJSONPal exists to give developers a fast, capable JSON studio that respects one non-negotiable rule: your data stays on your machine.

Why we built it

Working with JSON usually means juggling half a dozen tabs and pasting sensitive payloads into third-party websites. We wanted a single place that could format, validate, auto-repair, minify, and convert JSON — with a clean interface, instant results, and complete privacy. Everything here runs in your browser through a Web Worker, so even multi-megabyte documents are processed quickly without freezing the page.

What MyJSONPal offers

Privacy by design

Privacy isn't a feature we bolt on — it's the foundation of the product. There are no accounts, no sign-ups, no usage quotas, and no telemetry that sees your content. Paste, work, close the tab, and it's gone.

Free forever

All tools on MyJSONPal are free to use without limits or registration. The project is maintained by a small independent developer who believes developer utilities should be open, fast, and private by default.
