XML Input

C Output

What is XML to C Converter?

Working with C and need structs from XML? This tool generates clean C code with structs. Perfect for C projects in embedded systems, system programming, or low-level applications where you're working with XML data.

Instead of manually writing C structs and parsing logic, paste your XML and get ready-to-use code. The converter handles nested structures, arrays, and all the C-specific details automatically.

Everything runs locally in your browser. Your XML never leaves your machine – generate, download, and start using the structs right away.

What Makes This Tool Different

Automatic Struct Generation

Analyzes your XML and generates C structs automatically. Elements become structs, attributes become struct members, everything gets proper C types.

Type Detection

Automatically detects C types: char arrays for strings, int for numbers, pointers for nested structures. Arrays become fixed-size arrays or pointers.

Header File Support

Generate proper C header files with include guards and forward declarations. Ready to use in your C projects immediately.

File Upload Support

Got a big file? Just upload it. Works great for converting those massive XML configs or data files without copy-pasting.

Download C File

One click to download your C header file. Drop it into your C project and start using it. Perfect for embedded systems or system programming.

Clean Code Output

The generated C code is clean and well-formatted. Structs are properly named, members are typed correctly, and the code follows C conventions.

How It Works

1

Paste or Upload XML

Paste your XML into the left editor, or click "Upload" to load a file. The XML should be valid – use our XML Validator first if you're not sure. You can also click "Sample" to see an example.

2

Configure Options

Set your struct name and configure options. These settings customize the generated C code to match your project's conventions.

3

Download or Copy

Click "Download" to save the C file, or "Copy" to copy it to your clipboard. The C code is ready to use in your project. Drop it into your C project and start using it.

When You'd Actually Use This

Embedded Systems

Generate C structs from XML configs for embedded systems. Create data structures for XML-based configurations or device settings. Perfect for microcontroller programming.

System Programming

Create C structs from XML data for system-level applications. Generate data models for XML-based APIs or configurations. Perfect for low-level C programming.

Legacy Code Integration

Generate C structs from XML data for legacy C applications. Create data models for XML-based integrations or configurations. Perfect for maintaining legacy systems.

Code Generation

Generate C code from XML data structures. Perfect for creating data models, configuration structs, or data definitions from XML schemas.

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.

How are XML elements handled?

XML elements become C structs. Attributes become struct members, and nested elements become nested structs or pointers. Arrays become fixed-size arrays or pointers.

Can I use the generated C code?

Yes. The generated C code is valid and ready to use. Drop it into your C project and start using it. You may want to review and refine the structs for your specific use case.

What about memory management?

The generated structs are basic C structures. You'll need to handle memory allocation and deallocation yourself, as is standard in C programming.

Does it work with large XML files?

Yep. Since everything happens in your browser, it depends on your device. Small to medium XML structures convert instantly. Really huge structures might take a few seconds.

What C standard is supported?

The generated code works with C99 and later. It uses standard C features and follows C conventions for maximum compatibility.
