JSON Formatter & Validator

Minified → Beautified:

Input: {"name":"John","age":30,"city":"New York"}

Output:

{
  "name": "John",
  "age": 30,
  "city": "New York"
}

Array formatting:

[
  {
    "id": 1,
    "name": "Product A"
  },
  {
    "id": 2,
    "name": "Product B"
  }
]

Common Syntax Errors:

• Missing quotes: {name: "John"} → {"name": "John"}
• Trailing comma: {"name": "John",} → {"name": "John"}
• Single quotes: {'name': 'John'} → {"name": "John"}
• Unescaped strings: {"text": "He said "hello""} → {"text": "He said \"hello\""}

• API Development: Format API responses for better readability
• Configuration Files: Beautify config files like package.json, tsconfig.json
• Data Processing: Validate JSON data before processing
• Debugging: Format minified JSON for easier troubleshooting
