JSON Formatter

Summary

Paste raw or minified JSON and instantly pretty-print it with 2 or 4 space indentation. Validates and pinpoints syntax errors.

How it works

1. Paste or type your JSON into the input panel.
2. Select an indentation level: 2 spaces or 4 spaces.
3. Click Format (or press Ctrl+Enter) to pretty-print.
4. View the formatted output with character and line count stats.
5. Click Copy Output to copy the result to your clipboard.
6. Use Minify to collapse the JSON back to a single line.

Use cases

• Read API responses that arrive as a single minified line.
• Debug config files with deeply nested structures.
• Verify that a JSON payload is syntactically correct before sending.
• Standardize indentation across team members with different editors.
• Quickly count lines and characters in a JSON document.
• Convert between compact and readable forms during development.
