What this tool is for
JSON Formatter turns compact API responses, config snippets, and copied payloads into readable indented JSON.
When to use it
Use it before reviewing a response body, saving an example in documentation, or comparing nested keys by eye.
What the result means
The result is valid JSON with stable two-space indentation. Invalid JSON returns a parse message instead of guessing.
Use notes
- Paste a complete JSON value, object, or array.
- Quoted keys and strings must use standard JSON double quotes.
- Formatting changes whitespace only, not the data values.
Privacy and limits
