User Guide: Auto-Generating C# Classes from JSON Data

What is JSON to C# class Generation?

C# applications (.NET Core, ASP.NET) rely on object contracts to deserialize JSON strings from HTTP Clients or storage blocks. This compiler reads JSON entries, resolves primitive datatypes recursively, and formats C# classes complete with namespace structures, getters/setters, and package imports.

Step-by-Step Instructions

  1. Enter JSON: Paste your structured response list or object map inside the input panel.
  2. Choose Annotations: Toggle C# properties to use System.Text.Json (default in modern .NET) or Newtonsoft.Json attributes.
  3. Generate Class: The compiler outputs standard C# classes. Copy or download as a `.cs` file.

PascalCase Property Mapping and Namespace wrappers

C# style guidelines require variables to use PascalCase naming structures, whereas REST APIs typically return camelCase properties. Our converter formats property names to PascalCase automatically, keeping original API field maps registered via attribute decorators (e.g. [JsonPropertyName("...")]).
