What is XML to C# Converter?
Building .NET apps and need C# classes from XML? This tool generates clean C# POCO classes with XML serialization support. Perfect for .NET projects where you're working with XML data from APIs or config files.
Instead of manually writing C# classes and XML attributes, paste your XML and get ready-to-use code. The converter handles nested structures, XML attributes, and all the C#-specific details automatically. Works great with System.Xml.Serialization.
Everything runs locally in your browser. Your XML (eXtensible Markup Language) never leaves your machine – generate, download, and start using the classes right away.
How to Use XML to C#
Follow these steps to convert XML to C# classes. Each step uses the actual buttons and panels on this page.
Paste, Upload, or Load Sample
Paste XML into the left XML Input panel, or click Upload to load a file. Click Sample to load example telecomm XML. Example:
<subscribers><subscriber><subscriberId>SUB-1001</subscriberId><plan>Unlimited 5G</plan><dataUsage>45.2</dataUsage></subscriber></subscribers>Use Clear to start fresh. Validate first with our XML Validator if needed.
Configure Options
Set Class Name, Package, Data Class, and Nullable Types in the config panel. The right C# Output panel shows POCO classes with XML serialization attributes per the W3C XML specification.
Download or Copy
Click Download to save the .cs file, or Copy to copy to your clipboard. All processing runs in your browser – your XML never leaves your computer.
When You'd Actually Use This
API Integration
Generate C# classes from XML API responses. Perfect for creating DTOs (Data Transfer Objects) when integrating with SOAP APIs or XML-based web services.
.NET Development
Quickly create POCO classes for XML deserialization in .NET applications. Works great with ASP.NET Core, WCF services, and other .NET frameworks that use XML.
Configuration Files
Convert XML configuration files (like app.config, web.config) to strongly-typed C# classes. Makes configuration management type-safe and easier to work with in .NET applications.
Code Generation
Save time by generating C# classes automatically instead of writing them manually. Especially useful for complex nested XML structures with many elements and attributes.
Common Questions
Is my XML data stored?
Nope. Everything happens right in your browser. Your XML never leaves your computer – we don't even see it. Check out the W3C XML Specification for more details.
What C# features are supported?
The generator creates C# classes with properties (or fields), proper naming conventions (PascalCase), List<T> for arrays, XML Schema serialization attributes ([XmlElement], [XmlAttribute], [XmlText]), and support for nested elements. You can choose between properties with get/set or public fields, and enable nullable types.
How are nested elements handled?
Nested XML elements become separate C# classes. Each nested element gets its own class definition with [XmlElement] attributes, and the parent class references it as a property. Arrays of elements become List<T> where T is the generated class.
How are XML attributes handled?
XML attributes are converted to C# properties with [XmlAttribute] attributes. This ensures proper serialization and deserialization when working with XML documents.
Can I customize the generated classes?
Yes! You can change the root class name, choose between properties and fields, and enable/disable nullable types. The generated code follows C# conventions and includes XML serialization attributes.
What XML serializers work with these classes?
The generated classes work with System.Xml.Serialization.XmlSerializer (built into .NET). Just use XmlSerializer.Deserialize(stream) or XmlSerializer.Deserialize(reader).
