About JSON Formatter
The JSON Formatter validates and pretty-prints JSON in your browser. Nothing is uploaded to a server, so you can safely format config files, API responses, and payloads while debugging.
How to use
- Paste your JSON into the input box.
- Click Format / Validate to pretty-print or see syntax errors.
- Copy the formatted or minified output as needed.
Example
{"name":"iMirekal","tools":true} becomes indented, readable JSON with clear structure.
