About JSON Formatter and Validator

Check JSON syntax, pretty-print it, or remove unnecessary whitespace. A valid document can still fail an application-specific schema.

How to use it

  1. Paste JSON data.
  2. Choose validate only, pretty print, or compact output.
  3. Run the tool and review any syntax error.

Frequently asked questions
