JSON to C# Class Converter
Convert JSON objects into C# classes with nested models and lists for .NET developers.
Paste a JSON object to generate C# property classes. Adjust namespace, root class name, and nullable reference style.
JSON is converted in your browser; it is not uploaded.
Use cases
- Bootstrap DTOs from sample API responses.
- Create quick models for prototypes and spike solutions.
- Teach JSON mapping in onboarding workshops.
Frequently asked questions
Are property names PascalCase?
Yes. JSON keys are converted to PascalCase C# property names.
How are arrays handled?
Arrays become List<T> with T inferred from the first element when types are uniform.
Should I commit generated code blindly?
Review types, nullability, and naming before production use—generators infer heuristically.
