Does the ByteKiln C# to JSON converter support nested classes?
Yes. Known nested types are recursively expanded into example objects. Collections like List<T> and arrays become sample JSON arrays with one representative element.
Generate sample JSON from C# classes, including nested classes, dictionaries, and lists.
The ByteKiln C# to JSON converter reads your class definition and generates a representative JSON object with inferred sample values for each property. All processing happens in your browser — your code is never uploaded.
Each .NET type gets a sensible placeholder: strings become "sample", integers become 0, booleans become false, DateTimes become an ISO timestamp, and Guids become a sample UUID string.
Known nested class types are recursively expanded into nested JSON objects. List<T> and arrays are represented as single-element arrays containing one instance of the inner type.
Use it to generate example payloads for API documentation, Postman collections, or README examples — without manually writing JSON for every property in your model.
Short answers for the things developers usually ask before trusting a tool.
Yes. Known nested types are recursively expanded into example objects. Collections like List<T> and arrays become sample JSON arrays with one representative element.
No. The tool generates example JSON payloads based on your class structure. It is a design and documentation aid, not a runtime serializer like System.Text.Json or Newtonsoft.Json.
It maps common .NET types: string, int, long, double, decimal, bool, DateTime, Guid, and nullable variants. Unknown types are represented as empty objects.
No. The converter runs entirely in your browser. Your class definitions never leave your device and are never stored or transmitted.
Yes. Paste your request or response model and the tool produces a representative JSON example you can include in API specs, README files, or Postman collections.
Useful follow-ups when one conversion usually turns into three more.
Convert JSON payloads into C# classes with nested types, arrays, DateTime, and Guid detection.
Generate CREATE TABLE statements from C# classes for SQL Server, MySQL, and PostgreSQL.
