Format, validate, and inspect JSON
JSON is easy for software to exchange but difficult for people to inspect when it arrives as one compressed line. This JSON beautifier turns valid JSON into structured, indented output and clearly reports syntax problems when the input cannot be parsed.
What does the JSON Beautifier do?
It validates JSON, formats it with readable indentation, and can minify it again for compact storage or transfer. The formatted result can be copied or downloaded as a JSON file. The tool parses data only; it does not execute code contained in a value.
How to beautify JSON
- Paste a JSON object or array into the Input area.
- Select Beautify for readable indentation or Minify for compact output.
- If an error appears, correct the indicated JSON syntax and try again.
- Copy the result or download it when ready.
Who can benefit?
Developers, API testers, QA engineers, analysts, and technical writers can use it to inspect API responses, configuration files, structured logs, and sample payloads. It is especially handy when debugging a missing comma, quote, bracket, or other small formatting error.
Is JSON formatting private?
Yes. The input is processed in your browser and is not uploaded by this page. Even so, always follow your organization’s rules when handling credentials, personal information, production data, or other sensitive material.
