How to Convert XML to Kotlin Data Classes - Step by Step Guide

Step 1

Input Your XML Schema

Start by adding your XML data that needs to be converted to Kotlin data classes. The tool will analyze the XML structure and generate Android-ready Kotlin code:

•

Paste XML: Copy and paste your XML data directly into the editor

•

Upload XML file: Click upload to select XML files from your computer

•

Try sample data: Click "Sample" to load example XML and see the conversion

Step 2

Automatic Kotlin Data Class Generation

The tool automatically analyzes your XML structure and generates Kotlin data classes with serialization:

•

Null safety: Generated data classes follow Kotlin's null safety with nullable properties

•

Serialization support: Automatic @Serializable and @SerialName annotations

•

Android ready: Perfect for Android development and Kotlin multiplatform projects

Step 3

Get Generated Kotlin Code

Watch the magic! Your XML structure becomes null-safe Kotlin data classes with serialization support.

Kotlin Code Output

Your XML becomes these Kotlin data classes:

import kotlinx.serialization.Serializable
import kotlinx.serialization.SerialName

@Serializable
data class Root(
    @SerialName("id")
    val id: String? = null,
    @SerialName("profile")
    val profile: Profile? = null
)

@Serializable
data class Profile(
    val firstName: String? = null,
    val lastName: String? = null,
    val age: Int? = null
)

Step 4

Copy or Download Kotlin Code

Perfect! Now you can use your Kotlin data classes in your Android applications for XML processing.

•

Copy to clipboard for immediate use in your Android projects

•

Download .kt file for integration into your codebase

•

Use with frameworks like Retrofit and Room

•

Data processing and XML parsing workflows in Android

Example: Converting User Data XML to Kotlin

Let's say you have user data from an API in XML format:

<?xml version="1.0" encoding="UTF-8"?>
<user id="USER-001">
  <profile>
    <firstName>John</firstName>
    <lastName>Doe</lastName>
    <age>28</age>
    <verified>true</verified>
  </profile>
</user>

After conversion, you'll get Kotlin data classes like this:

import kotlinx.serialization.Serializable
import kotlinx.serialization.SerialName

@Serializable
data class Root(
    @SerialName("id")
    val id: String? = null,
    @SerialName("profile")
    val profile: Profile? = null
)

@Serializable
data class Profile(
    val firstName: String? = null,
    val lastName: String? = null,
    val age: Int? = null,
    val verified: Boolean? = null
)

What is XML to Kotlin Conversion? 🔄

XML to Kotlin conversion transforms XML document structures into Kotlin data classes optimized for Android development. This process analyzes XML elements, attributes, and hierarchical structure to generate type-safe Kotlin code with serialization annotations and proper null safety.

The generated Kotlin data classes include kotlinx.serialization annotations, nullable properties for XML attributes and elements, and nested data class definitions, making it easy to work with XML data in Android applications and Kotlin multiplatform projects.

Frequently Asked Questions

What Kotlin features are included in the generated data classes?

The tool generates modern Kotlin data classes with null safety, proper imports, and serialization annotations using kotlinx.serialization. Classes include automatic type inference from XML data, nested data class support for complex structures, and utility annotations for XML serialization and deserialization.

Are the generated Kotlin data classes compatible with Retrofit and Room?

Yes! The generated Kotlin data classes work perfectly with Retrofit as request/response models and can be easily integrated with Room database entities. They include proper serialization annotations that work seamlessly with modern Android development frameworks and API communication.

How does the tool handle complex XML hierarchies in Kotlin?

Complex XML structures are converted to nested Kotlin data classes with proper null safety relationships. Each XML element becomes a Kotlin data class with appropriate type annotations, maintaining the hierarchical structure while providing idiomatic Kotlin access to data through properties and standard Kotlin patterns.

What Android and Kotlin versions are supported by the generated code?

The generated Kotlin code is compatible with Kotlin 1.5 and higher versions, supporting Android API level 21+. It uses modern Kotlin features like data classes, null safety, and serialization annotations, making it suitable for contemporary Android development while maintaining compatibility with widely-used Android versions.

Can I use the generated classes for XML parsing and validation in Android?

Absolutely! The generated data classes include kotlinx.serialization support, allowing you to parse XML documents directly into typed Kotlin objects in your Android app. The classes also support validation through Kotlin's type system and can serialize objects back to XML format for API communication.

Is the XML to Kotlin converter free with unlimited usage?

Yes, completely free with no restrictions on XML complexity, file size, or usage frequency. Generate unlimited Kotlin data classes from XML schemas without registration, and download the complete Kotlin source code for immediate integration into your Android projects.
