What is XML to Kotlin Converter?
Building Android apps and need Kotlin data classes from XML? This tool generates clean Kotlin code with data classes. Perfect for Android development where you're working with XML data from APIs or config files.
Instead of manually writing Kotlin data classes and parsing logic, paste your XML (eXtensible Markup Language) and get ready-to-use code. The converter handles nested structures, nullable types, and all the Kotlin-specific details automatically.
Everything runs locally in your browser. Your XML never leaves your machine � generate, download, and start using the classes right away. Check out the W3C XML Specification for more details.
How to Use XML to Kotlin
Follow these steps to convert XML to Kotlin data 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 Class Name, Package, and Options
Set Class Name, Package, Data Class, and Nullable Types in the config panel. The right Kotlin Output panel shows data classes instantly per the W3C XML specification.
Download or Copy
Click Download to save the Kotlin 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
Android Development
Generate Kotlin data classes from XML API responses for Android apps. Create models for SOAP APIs or XML-based configurations. Perfect for Android development with Retrofit or OkHttp.
Spring Boot
Create Kotlin data classes from XML data for Spring Boot applications. Generate data models for XML-based APIs or configurations. Perfect for Spring Boot's XML support.
Kotlin Multiplatform
Generate Kotlin data classes from XML data for Kotlin Multiplatform projects. Create shared data models for XML-based APIs across iOS, Android, and other platforms.
Code Generation
Generate Kotlin code from XML data structures. Perfect for creating data models, DTOs, or entity classes from XML schemas or API responses.
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 elements become Kotlin data classes. Attributes become class properties, and nested elements become nested data classes or references. Arrays become Kotlin lists. Check out the XPath for more details.
Can I use the generated Kotlin code?
XML Yes. The generated Kotlin code is valid and ready to use. Drop it into your Kotlin project and start using it. You may want to review and refine the classes for your specific use case.
What about data classes?
XML 1.0 Specification You can enable data classes in the configuration options. This generates Kotlin data classes with automatic equals(), hashCode(), toString(), and copy() methods.
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 Kotlin version is supported?
The generated code works with Kotlin 1.3 and later. It uses standard Kotlin features and data classes for maximum compatibility.
