JSON to C# Classes

Generate starter C# model classes from a JSON sample. JSON Toolkit detects nested objects, arrays, nullable values, and safe property names directly in your browser.

How it works

Paste JSON

Use a real sample response or a simplified object with the fields your app expects.

Choose C#

Select C# Classes and set a root class name such as RootModel, ApiResponse, or UserProfile.

Copy code

Copy the generated classes and adjust naming, validation, or serialization attributes for your project.

Best for starter models

The generated code is a practical starting point for APIs and data transfer objects. Review types and naming before using it in production code.
