What is XML to C Converter?
Working with C and need structs from XML? This tool generates clean C code with structs following the W3C XML specification. 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 (eXtensible Markup Language) 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. Check out the W3C XML Specification for more details.
How to Use XML to C
Follow these steps to convert XML to C structs. 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 unsure.
Configure Class Name and Package
Use the config panel to set Class Name, Package, Data Class, and Nullable Types. The right C Output panel shows generated structs instantly per the W3C XML specification.
Download or Copy
Click Download to save the C header 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
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 Schema never leaves your computer – we don't even see it.
How are XML elements handled?
XML 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?
XML 1.0 Specification 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?
XML Schema 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.
