📚 What is JSON?

JSON (JavaScript Object Notation) is a lightweight data format. Example: {"name":"John","age":30}

💡 Format vs Minify

Format makes JSON readable with indentation. Minify removes all spaces for smaller size.

✅ Validation

Checks if JSON is valid. Common errors: missing commas, trailing commas, unquoted keys.

🔒 Privacy

All processing happens in your browser. Your JSON data is never sent to any server.
