What is JSON Formatter?

Tidies up JSON that sits on one line so it is easy to read, and finds syntax errors.

How to use

  1. Paste your JSON.
  2. Click format or minify.
  3. If there is an error, fix the position that is marked.

Tips

  • A comma after the last item and single quotes are errors in JSON.
  • Your data is processed only in the browser and never leaves it.
