XML to C# Converter

XML is a attribute-rich, namespace-aware hierarchical document format — widely used for SOAP APIs, RSS/Atom feeds, Android layouts, enterprise data exchange. Converting it to strongly-typed C# structures eliminates runtime surprises and speeds up development. This tool does it in one click, entirely in your browser.

How to use this converter

1. Paste your XML into the left editor panel
2. Click Generate
3. Copy the generated C# code from the right panel

No account. No upload. No tracking. Runs entirely in your browser.

The problem with manual XML-to-C# mapping

C# is a object-oriented, strongly typed language — typed data models are central to how it works. Yet copying fields from XML payloads into C# class / record definitions introduces subtle errors:

• Mistyped field names cause silent deserialization failures
• Missing optional fields trigger runtime panics or null errors
• Schema drift between API and model goes undetected until production

C# records (C# 9+) provide immutable, value-semantic data models — ideal for DTOs in modern .NET applications.

This converter eliminates the manual step entirely.

C# and XML: what you need to know

C# is a object-oriented, strongly typed language, .NET standard for ASP.NET Core, Unity, and enterprise apps. It uses class/record based with System.Text.Json or Newtonsoft for structured data — making it a natural fit for XML-driven applications.

What the converter generates

The output consists of C# records or classes with [JsonPropertyName] attributes. This is the idiomatic pattern for C# data models, compatible with popular C# serialization libraries.

A common gotcha

C# nullable reference types (string?) require the #nullable enable directive — the converter targets modern C# 10+ conventions.

XML input characteristics

XML allows mixed content (text + child elements), namespaces, and CDATA sections — more expressive but more verbose than JSON. XML is the foundation of many enterprise integration standards including XSLT, XSD, and SOAP.

Common use cases

• Validating XML contract compatibility with C# type definitions
• Generating C# models from ASP.NET Core APIs API responses
• Creating typed DTOs for Unity games
• Rapid prototyping with real XML payloads
• Keeping C# structs in sync when XML schemas evolve
• Onboarding new team members by auto-generating the data layer

Frequently asked questions

What serialization library does the generated C# code assume?

The generated code is compatible with the standard C# serialization ecosystem — C# records or classes with [JsonPropertyName] attributes. No unusual dependencies required.

What version of C# does the output target?

The converter targets modern C# conventions — C# records or classes with [JsonPropertyName] attributes. If you need output for an older version, the generated code can typically be adapted with minor changes.

Is my XML data sent to a server?

No. All conversion runs locally in your browser using client-side JavaScript. Your XML data never leaves your machine.

What XML inputs does this converter accept?

Paste any valid XML — including SOAP APIs, RSS/Atom feeds, Android layouts, enterprise data exchange. The converter infers types and generates a matching C# model.
