This tool transforms JSON into high-quality C# classes or records, suitable for use in .NET and .NET Core applications. It handles nested objects, arrays, and various primitive types, creating a clean, strongly-typed structure that is perfect for model binding in ASP.NET Core APIs or client-side applications. The tool also supports generating attributes for popular JSON libraries like Newtonsoft.Json or System.Text.Json, ensuring that your C# models are consistent with your data sources and easy to manage throughout your project.

Paste your JSON to generate C# classes. It includes `JsonProperty` attributes for Newtonsoft.Json or `JsonPropertyName` for System.Text.Json.

C# developers frequently need to map complex JSON responses to strongly-typed classes for better IDE support and runtime safety. This tool automates this repetitive process, ensuring your C# models are perfectly aligned with your JSON data and significantly reducing the amount of manual boilerplate code you need to write.

Example Input

{
  "id": 1,
  "name": "John Doe",
  "email": "john@example.com",
  "isActive": true,
  "tags": ["admin", "dev"],
  "profile": {
    "bio": "Software Engineer",
    "skills": ["Go", "React", "TypeScript"]
  }
}

Example Output

public class User {
    public int Id { get; set; }
    public string Name { get; set; }
    public string Email { get; set; }
    public bool IsActive { get; set; }
}

Namespace Missing

Fix: The tool generates the class. You'll need to wrap it in a `namespace` block in your project.

Does it support Record types?

Yes, you can choose to generate C# 9.0+ `record` types for immutable data models.
