Example

Try this sample JSON to test the formatter or other tools:

{
  "user": {
    "name": "John Doe",
    "email": "john@example.com",
    "preferences": {
      "theme": "dark",
      "notifications": true
    },
    "friends": [
      { "name": "Alice", "age": 28 },
      { "name": "Bob", "age": 32 }
    ]
  }
}

Try accessing user.friends.0.name to get "Alice" (Formatter/Path Finder).
