Developer Utility
JSON Formatter Tool
Prettify raw JSON with consistent indentation.
Language: JSONUtility: Format
{ "hello": "world" }
What This Tool Does
Use this when logs or API payloads are hard to read and you need stable indentation for review.
Use it to inspect or transform input quickly, then carry validated output into code, tests, or API requests.
Common Use Cases
- Prettify webhook payloads before sharing in tickets.
- Normalize spacing before creating fixture files.
- Inspect deeply nested API responses during debugging.
Common Pitfalls
- Formatting does not fix invalid JSON syntax.
- Very large payloads can freeze lower-end devices.
