When to use json formatter
Use this workbench to inspect API examples, configuration and copied JSON documents. Formatting parses the input before producing two-space indentation, so invalid data produces an error instead of a misleading result. Minify removes unnecessary whitespace after parsing. A dark output panel makes nested values easier to read.
How it works
- Paste a JSON document.
- Choose Format or Minify.
- Copy or download the valid output.
Try this example
{"name":"Ada","active":true,"scores":[12,18]}Before you export or rely on the result
Parsing follows JavaScript JSON rules. Duplicate keys keep their last value, and integers beyond Number.MAX_SAFE_INTEGER can lose precision. Do not use this to preserve exact large numeric identifiers.
Does this tool upload my input?
No. This tool processes input in your browser. Optional advertisements are separate third-party content and load only when you allow ads. See the privacy notice for hosting logs and advertising details.
Can I use the result without creating an account?
Yes. JSON Formatter is free to use without an account. Review the result against the limits above and the requirements of the app or document where you plan to use it.
