How does JSON to C# work?

Converting **JSON to C#** involves analyzing the structure of a JSON object to determine property names and data types (string, int, boolean), and then generating a corresponding **C# Class** definition. This class (often called a POCO or DTO) allows developers to easily deserialize API responses into strongly-typed objects using libraries like `System.Text.Json`.

How to Generate C# Classes from JSON

  1. 1

    Paste JSON Response

    Get the raw JSON response from your API (e.g., from Postman or Swagger) and paste it into the editor.

  2. 2

    Configure Class Name

    (Optional) Set the Root Name to match your desired class name (e.g., `UserResponse`). The tool will use this for the main class.

  3. 3

    Copy C# Code

    The tool instantly generates the C# code. Click Copy and paste it directly into your Visual Studio `.cs` file.

Why use this Converter?

Type Safety

We automatically infer types. Text becomes `string`, numbers become `int` or `double`, and arrays are properly typed as `List<T>`.

Nested Objects

Complex JSON structures? No problem. We analyze the entire tree and generate every necessary child class to represent the full hierarchy.

Instant & Free

Stop writing boring boilerplate code by hand. Generate perfect DTOs in milliseconds, completely free and open source.
