JSON Formatter & Validator
Paste JSON to format or minify it. Syntax errors are shown immediately and the data never leaves this tab.
Runs entirely in your browser. This page is a static file. Whatever you type stays in the tab, is never sent to a server, and is gone when you close it — so pasting a real token or config is safe.
When you reach for this
- Reading compact API responses.
- Checking configuration syntax before deployment.
- Producing stable output with sorted object keys.

Frequently asked questions
