Why Convert JSON to C#?

In the .NET ecosystem, strong typing is king. When consuming REST APIs, you often receive JSON data that needs to be deserialized into C# objects (POCOs) before you can use it. Manually writing `public class MyModel {...}` for every API response is tedious, error-prone, and time-consuming.

Our **JSON to C# Converter** automates this process. Paste your raw JSON, and we instantly generate the corresponding C# class hierarchy, complete with proper types (`int`, `bool`, `string`, `List<T>`) and PascalCase naming conventions.

Key Features

Classes & Records

Choose between standard mutable `class` definitions or modern, immutable C# 9.0+ `record` types. Records are perfect for DTOs (Data Transfer Objects) where value-based equality is needed.

Nested Object Handling

If your JSON contains nested objects or arrays of objects, our tool recursively generates separate classes for them, keeping your code clean and modular.

Smart Type Inference

We analyze the values in your JSON to determine the correct C# type. `true` becomes `bool`, `123` becomes `int`, and arrays are converted to `List<T>`.

PascalCase Formatting

JSON usually uses `camelCase`, but C# follows `PascalCase`. We automatically capitalize property names to match standard .NET coding conventions.

Common Use Cases

  • API Integration: Quickly generate response models for `HttpClient.GetFromJsonAsync<T>()`.
  • Configuration Binding: Create strongly-typed classes to bind `appsettings.json` sections using `IOptions<T>`.
  • Entity Framework: Scaffold initial entity classes from valid JSON data samples.

Frequently Asked Questions

How does JSON to C# conversion work?

The tool analyses JSON structure and generates C# model classes with properties matching the data format.

Is it compatible with .NET projects?

Yes. Generated classes work with .NET Core and standard .NET applications.

Does it support nullable types?

Yes. Nullable fields are handled where applicable based on the JSON structure.

Can I customise property names?

You can edit the generated code after conversion to match your project conventions.
