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

  1. Paste your JSON into the input box.
  2. Click Format / Validate to pretty-print or see syntax errors.
  3. Copy the formatted or minified output as needed.

Example

{"name":"iMirekal","tools":true} becomes indented, readable JSON with clear structure.
