JSON Formatter & Beautifier

Format, beautify, validate, and minify JSON data instantly. Makes JSON readable and organized. Perfect for API development and debugging.

Why Format JSON?

📖 Readability

Properly formatted JSON with indentation is much easier to read and understand. Essential for debugging API responses.

🔍 Debugging

Formatted JSON makes it easy to spot errors, missing commas, unclosed brackets, and data structure issues.

✅ Validation

Instantly verify JSON syntax is correct. Catches common errors like trailing commas, unquoted keys, single quotes.

🚀 Performance

Minified JSON reduces file size by 20-30%, improving API response times and data transfer speeds.

Common Use Cases

  • API Development: Format API responses for easier debugging
  • Configuration Files: Beautify package.json, tsconfig.json, settings files
  • Data Analysis: Make large JSON datasets readable
  • Validation: Check JSON syntax before sending to server
  • Minification: Compress JSON for production deployment

FAQ

What's the difference between formatting and validating?

Formatting adds indentation and line breaks for readability. Validation checks if JSON syntax is correct (proper brackets, commas, quotes).

Does formatting change JSON data?

No! Formatting only changes whitespace. The data structure and values remain identical. JSON.parse() produces the same object.

Why is my JSON invalid?

Common issues: trailing commas, single quotes instead of double quotes, unquoted property keys, missing commas, unclosed brackets.

Should I minify JSON in production?

Yes for APIs and data transfers. Minified JSON is 20-30% smaller, reducing bandwidth and improving response times. Use formatted JSON for config files.
