Here's a typical test fixture and how JSON2FORM makes it editable:

test-user.json 
{
  "user": {
    "id": 12345,
    "email": "test@example.com",
    "name": "Test User",
    "isVerified": true,
    "role": "admin"
  },
  "mockResponse": {
    "status": 200,
    "success": true,
    "message": "User created successfully"
  },
  "testFlags": {
    "skipValidation": false,
    "mockPayment": true,
    "debugMode": true
  }
}
