Input JSON Data
C# Entity Class Code

Tool Guide & C# Class Generation Info

Tool Features

  • Pure Frontend Conversion: Millisecond response, directly converting complex JSON text into standard C# class structures right in the browser.
  • Smart Type Inference: Automatically infers int, double, bool, string, and complex List<T> based on JSON values.
  • Popular Framework Support: Supports adding Newtonsoft.Json (JsonProperty) or System.Text.Json (JsonPropertyName) attributes to properties, seamlessly integrating with modern .NET development.

C# Serialization Frameworks Comparison

  • Newtonsoft.Json: The most popular third-party JSON framework in the .NET ecosystem for a long time. Extremely powerful and highly fault-tolerant, but relatively large in size and memory footprint.
  • System.Text.Json: Microsoft's official built-in JSON framework since .NET Core 3.0. Focuses on extremely high performance and low memory allocation (based on Span<T>), and is currently widely recommended for new .NET projects.

Notes

  • In C#, it is generally recommended to declare class properties parsed from JSON as public and use PascalCase naming. Original JSON key names are mapped using Attributes.
