What does this JSON formatter do?
It parses your JSON and produces a clean, consistently indented result. You can also validate syntax without changing the content or minify valid JSON for compact storage and transfer.
How to use it
- Paste JSON into the input editor.
- Choose two spaces, four spaces or tabs.
- Select Format JSON, Minify or Validate.
- Copy the result when it is ready.
Limitations
The formatter accepts standard JSON. It cannot parse JavaScript object literals, comments, trailing commas, unquoted property names, undefined or NaN. Very large documents are still limited by your device’s available memory.
