About JSON Formatter
Use this tool to make compact JSON readable, reduce it for transport, or confirm that a payload is valid. Processing happens locally, so pasted API responses are not uploaded.
How to use
- Paste JSON into the input field.
- Choose pretty, minified, or sorted output.
- Copy the validated result.
FAQ
Does formatting change my values?
No. Formatting changes whitespace and, when selected, key order; values and data types remain the same.
