Tool guide
How to format JSON safely
Use the JSON formatter to make API data readable, inspect structure, and catch syntax problems before sharing or using JSON in code.
Recommended workflow
- Paste JSON into the input box and format it to reveal nested objects, arrays, and values.
- Fix syntax errors before copying the output into an API client, source file, or documentation.
- Minify only after the formatted version has been reviewed and validated.
Before relying on the result
- Do not paste secrets, API keys, private customer records, or production tokens into public tools.
- Validate generated JSON before committing it to code or sending it to an API.
- Keep sample payloads small enough to review manually.
