Convert XML to C# online, free. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. C# classes model data for .NET with System.Text.Json support. XML to C# conversion parses your XML against the W3C XML 1.0 grammar (https://www.w3.org/TR/xml/), builds an in-memory model of its keys, nested objects and arrays, then emits ready-to-use C# types with System.Text.Json attributes following the C# language reference conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include .NET APIs, desktop apps and Azure functions.
It maps the full structure of your XML onto idiomatic C# types, following the C# language reference conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste XML and generate C# types from C# immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested XML objects, tables and arrays are mapped faithfully onto C#, including nested types and optional fields.
Your XML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
A XML document and its C# equivalent:
XML input:
<product>
<sku>A-100</sku>
<price>19.99</price>
<active>true</active>
</product>Output:
public class Product
{
public string Sku { get; set; }
public double Price { get; set; }
public bool Active { get; set; }
}Paste your XML into the editor and press "Convert to C#". The tool parses it against the W3C XML 1.0 grammar, then generates C# types following C# language reference conventions — instantly and entirely in your browser. You can validate or format the XML first to be sure it is clean.
XML has no native numbers, booleans or arrays. Repeated child elements become lists in C#, attributes and element text become fields, and values stay strings unless C# coerces them — so review numeric or boolean fields after converting.
Optional or nullable members in the generated C# are inferred from keys missing in some records of your XML, following C# language reference. Include the optional fields in your sample so they are typed correctly.
XML (eXtensible Markup Language) (XML) — XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. C# classes (C#) — C# classes model data for .NET with System.Text.Json support. This converter maps the structure of your XML onto C# so you can use it for .NET APIs.
Yes. Invalid XML is flagged with a clear error before anything is converted. Common XML problems to check are matched start and end tags, a single root element, and quoted attribute values. Starting from clean input keeps the generated C# accurate.
Yes. The entire XML-to-C# conversion runs locally in your browser in JavaScript — your XML is never uploaded, logged or stored. That matters when the data is something like SOAP web services, which should not leave your machine.
The generated C# is ready for .NET APIs, desktop apps and Azure functions. Copy or download it and drop it straight into your codebase.
