Development C#

JSON to C# Classes Assistant

Analyze a JSON example and generate simple C# classes for API responses, data models, tests and integrations. Processing happens locally in the browser.

No code execution

The tool does not execute C# or JSON as a script. It only uses the browser JSON parser, derives types and generates C# class text.

What is this tool for?

The assistant creates starting points for simple data classes. Review the generated output before production use, especially with mixed arrays, optional fields, number ranges and date values.
