JSON Format/Validate

Format, validate, and beautify JSON with syntax highlighting

JSON Path: (e.g., $.store.book[*].author)

How it works

Paste or type JSON in the input panel. The tool will automatically:

  • Validate - Check for syntax errors and show helpful error messages
  • Format - Pretty-print with your chosen indentation
  • Highlight - Color-code keys, strings, numbers, and booleans
  • Navigate - Click any value to see its JSON Path

Use the Sample button to load example JSON, or Clipboard to paste from your clipboard.
