JSON to C# Code Generator

JSON to C# Class Converter – Generate C# Models from JSON

Use this free JSON to C# converter to instantly generate strongly typed C# classes from JSON objects. Paste your JSON, click convert, and the tool builds C# model classes with properties that match your JSON structure.

This is ideal when you’re consuming APIs in .NET or building data transfer objects and want to avoid hand-writing every property by yourself.

What the JSON to C# Converter Does

The CodersTool JSON to C# generator:

• Parses your JSON object or array and infers C# property types.
• Generates class definitions with public properties matching your JSON keys.
• Supports nested objects and arrays by creating additional C# types as needed.
• Produces code you can drop straight into your .NET, ASP.NET Core, or Unity projects.

How to Generate C# Classes from JSON

1. Paste your JSON

1. Copy the JSON from your API response, configuration, or sample payload.
2. Paste it into the input area of the JSON to C# converter.
3. Make sure it’s valid JSON (you can use the JSON Formatter tool if needed).

2. Click “Convert to C#”

1. The tool analyzes your JSON and infers appropriate .NET types like string, int, double, bool, DateTime, and collections.
2. It outputs one or more C# classes with properties named after your JSON fields.

3. Copy the generated C# code

1. Copy the class definitions into your project.
2. Use them with your JSON serializer (e.g., System.Text.Json, Newtonsoft.Json) to deserialize responses into strongly typed objects.

Example – JSON to C#

Input JSON

{
  "id": 1,
  "name": "Example",
  "isActive": true
}

Generated C# Class

public class Root
{
    public int Id { get; set; }
    public string Name { get; set; }
    public bool IsActive { get; set; }
}

You can rename the root class or properties to match your naming conventions, but the heavy lifting of mapping types is already done.
