JSON Formatter

How to format JSON for API debugging

Readable JSON shortens debugging sessions because nested objects, arrays, and booleans stop blending into one long line.

Start with a parsed copy

Paste the raw response into JSON Formatter and run Format JSON. If parsing fails, fix the line and column reported before editing the data.

Use 2-space indentation for quick inspection and 4-space indentation when pasting into documentation.

Keep review diffs stable

Enable key sorting when the producer does not guarantee object order. Stable ordering makes pull requests and notes easier to scan.

FAQ

Does formatting change API data?

No. Formatting only changes whitespace and, optionally, object key order.
