Convert JSON payloads into C# classes with nested types, arrays, DateTime, and Guid detection.
The ByteKiln JSON to C# generator parses your JSON, infers .NET types for each value, and outputs ready-to-compile POCO class definitions. The entire conversion runs in your browser with no server involved.
Strings become string, decimal numbers become double, whole numbers become int or long, and booleans become bool. ISO 8601 date strings are detected as DateTime and UUID-format strings become Guid.
Nested JSON objects generate a separate C# class per unique shape. Arrays of objects generate List<T> properties pointing to the inferred class. Arbitrary nesting depth is handled recursively.
Set a root class name before converting to replace the default "Root". After generating, review nested class names, add namespaces, and apply data annotations like [JsonPropertyName] for your codebase.
Short answers for the things developers usually ask before trusting a tool.
The generator infers string, int, long, double, bool, DateTime (ISO 8601 strings), Guid, and nullable variants. Nested objects become separate classes and arrays become List<T> properties.
Null values are typed as nullable string (string?) by default. The generator avoids double-nullable syntax and marks these properties clearly so you can refine the type later.
Use them as a starting point. The generated code covers common cases well, but you should review property names for naming conventions, add data annotations, and set appropriate namespaces for your codebase.
Yes. The generator recursively processes nested objects and creates a separate C# class for each distinct object shape found in the JSON structure.
No. The ByteKiln JSON to C# converter runs entirely in your browser. Your JSON payload never leaves your device and is not stored or logged.
Useful follow-ups when one conversion usually turns into three more.
