JSON Formatter

Beautify, minify, and validate JSON

JSON Input
FAQ
What does formatting do?
It turns compact one-line JSON into readable text with indentation and line breaks. Handy for reading API responses and config files.
When should I minify?
Minify removes all whitespace to reduce size, useful for transmission and storage.
Does it catch JSON errors?
Yes. Invalid JSON shows an error message and moves the cursor to the problem position.
Is my data sent anywhere?
No. Everything runs in your browser; your JSON is never transmitted or stored.
