Learn how to quickly convert JSON into C# class utilities using XLGen. Speed up your development process with simple, practical steps.
Generate C# Class Utilities from JSON with XLGen
Working with APIs and data formats often means needing to convert JSON into strongly typed C# classes. Manually handling these conversions can be tedious and prone to errors. With XLGen, you can automate this process and generate C# class utilities directly from JSON, giving you more time to focus on core development tasks.
Why Convert JSON to C# Classes?
Defining C# classes from JSON data helps you:
Strongly type your objects for safer, intellisense-enabled coding
Easily deserialize JSON responses from APIs
Maintain synchronization between backend contracts and your .NET models
Using XLGen’s Converter with JSON and C#
Here’s how simple it is to use XLGen for your JSON-to-C# needs:
Visit the XLGen Converter page.
Select the JSON to C# tool from the list of available converters.
Paste your JSON data into the input box.
Click “Convert”.
Copy the generated C# class code and add it to your project.
Example:
{
"id": 1,
"name": "XLGen",
"active": true
}
After conversion, XLGen produces:
public class Root {
public int Id { get; set; }
public string Name { get; set; }
public bool Active { get; set; }
}
Customize Your C# Class Output
XLGen automatically detects property names and types. For more complex JSON structures, such as arrays or nested objects, XLGen handles the mapping by generating additional classes. This provides immediate, editable code ready for implementation in your projects.
