JSON to CSharp Class

Convert JSON payload samples into C# class models with inferred nested types.

About JSON to CSharp Class

JSON to CSharp Class converts sample JSON into starter C# classes with nested type inference and PascalCase properties. It adds `JsonPropertyName` attributes where original keys differ, helping preserve wire compatibility while keeping C# naming idiomatic. This is useful for API modeling, DTO bootstrapping, and rapid backend/client integration work.

Why use JSON to CSharp Class

  • Scaffold C# models fast
  • Preserve JSON key mapping cleanly
  • Handle nested objects and arrays automatically

How to use JSON to CSharp Class

  1. Set root class name
  2. Paste JSON sample
  3. Generate and copy C# output
