Convert XML to Kotlin online, free. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. Kotlin data classes model structured data with null-safety. XML to Kotlin conversion parses your XML against the W3C XML 1.0 grammar (https://www.w3.org/TR/xml/), builds an in-memory model of its keys, nested objects and arrays, then emits ready-to-use Kotlin types as data classes with nullable types following the Kotlin docs conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include Android apps, Ktor services and kotlinx.serialization.
It maps the full structure of your XML onto idiomatic Kotlin types, following the Kotlin docs conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste XML and generate Kotlin types from Kotlin immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested XML objects, tables and arrays are mapped faithfully onto Kotlin, including nested types and optional fields.
Your XML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
Example: XML → Kotlin
@Serializable
data class User(
val name: String,
val age: Int,
val email: String? = null,

XML (eXtensible Markup Language) (XML) and Kotlin data classes (Kotlin) are different serialization formats, each with its own syntax and strengths. Data often needs to move between them when integrating tools, APIs, or configuration systems that expect a specific format. This converter maps the structure of your XML onto valid Kotlin so you can use it wherever Kotlin is required.
