About the JSON Formatter

A free JSON formatter and validator. Paste JSON to pretty-print it, catch syntax errors, and copy the clean result.

How to use the JSON Formatter

  1. Paste the JSON into the editor.
  2. Format or validate it.
  3. Copy the result, or fix the line the validator marks.

What to check

The tool checks structure. It does not know whether the field names match an API you are calling.

Does the JSON formatter upload my data?

The JSON is formatted in your browser.

Can it repair broken JSON?

It reports the error. You still need to fix missing commas, quotes, or brackets.
