How to use JSON Formatter
- Paste a complete JSON value into the input area.
- Choose Format for readable indentation, or Minify to remove unnecessary whitespace.
- Review the output or the reported parsing error before using it in your application.
Practical example
An object such as {"name":"Ali","active":true} can be formatted onto several lines without changing those values.
What to check before using the result
Valid JSON needs quoted property names and does not allow comments or trailing commas. Formatting does not validate your application schema, detect every duplicate key or make untrusted data safe. Parsing can round integers beyond JavaScript safe-integer precision; keep exact large identifiers in strings.
