Format your JSON

How to use this JSON formatter

Use the editor to validate and reshape JSON in three simple steps.

  1. Paste or type valid JSON into the input editor.
  2. Choose Format / Pretty Print for readable indentation or Minify for compact JSON.
  3. Copy the output when you are ready to use it elsewhere.

Frequently asked questions

Is my JSON sent to a server?
No. Formatting and minifying happen entirely in your browser, so the JSON you paste stays on your device.
What happens when my JSON is invalid?
The formatter reports that the JSON is invalid and clears the previous output, while leaving your input in place so you can correct it.
Does the formatter preserve Unicode text?
Yes. The browser’s native JSON parser and stringifier retain Unicode text naturally when processing valid JSON.
