About this Tool
Generate strongly-typed C# classes from JSON payloads instantly.
1Why Generate C# Classes?
Manually writing C# classes and properties for complex JSON structures is time-consuming and error-prone, especially when dealing with deeply nested API responses. This generator parses your JSON, infers data types, and creates perfectly formatted C# POCOs (Plain Old CLR Objects) ready for deserialization using System.Text.Json or Newtonsoft.Json.
2Example: JSON to C# Class
Input JSON: ```json { "orderId": "ORD-123", "total": 59.99 } ``` Output C#: ```csharp public class Root { public string orderId { get; set; } public double total { get; set; } } ```
3Modern C# Features
The generated code follows modern C# naming conventions and can be configured to use `get; set;` properties. It automatically handles type mapping for strings, integers, doubles, booleans, and complex nested objects or lists.
4Privacy: Your Schemas are Safe
Your proprietary JSON data and internal models are never sent to a server. The C# code generation logic runs entirely offline in your browser, ensuring your business logic remains strictly confidential.
Privacy Guarantee
Secure Devutils operates exclusively in your browser using local web workers and JavaScript. Your source code, configurations, and sensitive text payloads are never transmitted across the network or stored on any external servers. It is completely safe for air-gapped environments.
