JSON Formatter
Format, beautify, or minify JSON in your browser. Validate and pretty-print instantly — no upload, free online JSON formatter.
Format and minify JSON privately
Paste JSON, beautify it for readability, or minify it for transport. Everything runs locally in your browser.
What you can do with it
- Debug an API response
- Pretty-print a raw JSON payload so nested fields are easy to scan.
- Prepare a compact config
- Minify JSON before embedding it in a URL or config file.
How to format JSON
- Paste your JSON into the editor.
- Click Format to beautify or Minify to compact it.
- Copy the result to your clipboard.
Pretty-print JSON without pasting secrets into a remote tool
API payloads and config dumps often contain tokens. Formatting in the browser means those strings never leave your machine — safer than public “JSON beautifier” sites when debugging production responses.
Format vs minify
Format for reading nested objects. Minify when you need a single-line payload for a query string, environment variable, or compact log line.
