About this tool
Generate a basic C# class with properties inferred from JSON values. Processing happens locally in your browser, so your input is not sent to a server or included in analytics.
Frequently asked questions
Does it generate JSON serialization attributes?
No. It creates basic auto-properties without serializer-specific annotations.
How are nested objects represented?
Nested objects use Dictionary<string, object>; arrays use the inferred first item type.
Is the JSON uploaded?
No. Generation happens in the browser.
