About JSON Formatter
Pretty-print JSON for readability or minify it for compact storage. Validates JSON syntax and reports errors with line numbers.
How It Works
The tool parses your JSON using the browser's built-in JSON.parse(), then re-serializes it with JSON.stringify(). Format mode uses indentation for readability. Minify mode removes all whitespace for the smallest output.
Step by Step
- 1 Paste your JSON data
- 2 Choose Format (pretty-print) or Minify (compact)
- 3 Adjust indent level for formatting (default: 2 spaces)
- 4 Click Format / Minify
Tips
- Use 2-space indent for compact formatting, 4-space for more readable output.
- Minified JSON is useful for API requests and configuration files.
- If parsing fails, check for trailing commas or missing quotes.
Frequently Asked Questions
Does it validate the JSON?
Yes. If the JSON is invalid, the tool shows the error message from the parser.
