JSON Formatter
Use the free JSON Formatter to format, validate, convert or generate developer data instantly in your browser. Fast and no signup.
How to use JSON Formatter
- Paste or enter the source data or website information.
- Run the checker, formatter, converter or generator and review the output.
- Copy or download the result, then test it in your actual website or development workflow.
Format and validate JSON together
Paste JSON into the tool to parse it and output a readable indented version. Invalid JSON is rejected instead of being silently “fixed”, which makes the formatter useful for API responses, configuration snippets and debugging.
Do not paste production secrets, passwords or private tokens into any online tool unless you understand where the data is processed. This formatter is browser-based, but the safest practice is still to avoid unnecessary secret handling.
