JSON Formatter
Beautify, validate and minify JSON with clear error reporting.
Reading raw JSON straight from an API response is hard on the eyes — one missing comma and the whole payload is a wall of text. Paste it here and the formatter re-indents everything into a clean, readable tree, then flags exactly where any syntax error sits so you can fix it fast.
What you can do with it
- Beautify compact API output into properly indented, scannable JSON.
- Validate structure before you ship it to a config file or request body.
- Minify the same data back down when you need the smallest possible payload.
Everything is processed locally in your browser, so even sensitive response data never leaves your machine.
