About JSON formatting
JSON formatting makes data easier to read and debug. This tool can pretty-print JSON with indentation and validate it to catch syntax errors.
How to use
- Paste your JSON into the input box.
- Click Format to pretty-print, or run validation if available.
- Copy the formatted JSON for logs, APIs, or configuration files.
Common errors
- Missing quotes around keys or string values.
- Trailing commas (not allowed in standard JSON).
- Unmatched brackets or braces.
