Visual Studio: Paste JSON as Classes – Generate C# Models Instantly

- 07.06.26 - ErcanOPAK

📋 Copy JSON, Paste C# Classes

API returns JSON? Need C# model? Edit → Paste Special → Paste JSON as Classes generates everything. No manual typing.

📝 How to Use

1. Copy JSON from browser / API response
2. In Visual Studio: Edit → Paste Special → Paste JSON as Classes
3. VS generates proper C# classes with:
   - Properties with correct types
   - JsonPropertyName attributes
   - Nested classes for nested objects
   - Array handling

Example input:
{
  "id": 1,
  "name": "Alice",
  "email": "alice@example.com",
  "address": {
    "city": "New York",
    "zip": "10001"
  }
}

VS generates:
public class Root
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Email { get; set; }
    public Address Address { get; set; }
}

public class Address
{
    public string City { get; set; }
    public string Zip { get; set; }
}

✅ Also Works For

  • Paste XML as Classes: Generate from XML samples
  • Perfect for REST API integration
  • Saves hours of manual model creation
  • Handles complex nested structures

“API documentation had JSON sample. Copied, pasted as classes, 100 lines of models generated instantly. Saved 30 minutes of typing. VS feature I never knew existed.”
