About the JSON Beautifier
This tool formats JSON so it is easy to read. It indents nested objects and arrays, puts each key on its own line, and validates your JSON in the process.
Why beautify JSON?
- Readable API responses — see the structure at a glance.
- Easier diffing — compare configuration files.
- Error detection — invalid JSON shows a clear message.
