About the JSON Formatter

The JSON Formatter parses the complete document before presenting a consistently indented version. Parsing first ensures that a visually tidy result is also valid JSON.

How to use the JSON Formatter

  1. Paste a JSON object or array.
  2. Choose two spaces, four spaces or tabs.
  3. Format and correct any error location reported by the parser.

Practical tips

  • JSON property names and string values require double quotes.
  • Download the formatted result with a .json extension when it is ready.
