Convert XML to TypeScript online, free. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. TypeScript interfaces give compile-time types for data crossing your app. XML to TypeScript 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 TypeScript types as interfaces with optional members following the TypeScript Handbook 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 typed API clients, React/Next.js props and shared front/back types.
It maps the full structure of your XML onto idiomatic TypeScript types, following the TypeScript Handbook 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 TypeScript types from TypeScript 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 TypeScript, 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.
A XML document and its TypeScript equivalent:
XML input:
<product>
<sku>A-100</sku>
<price>19.99</price>
<active>true</active>
</product>Output:
interface Product {
sku: string;
price: number;
active: boolean;
}Paste your XML into the editor and press "Convert to TypeScript". The tool parses it against the W3C XML 1.0 grammar, then generates TypeScript types following TypeScript Handbook conventions — instantly and entirely in your browser. You can validate or format the XML first to be sure it is clean.
XML has no native numbers, booleans or arrays. Repeated child elements become lists in TypeScript, attributes and element text become fields, and values stay strings unless TypeScript coerces them — so review numeric or boolean fields after converting.
Optional or nullable members in the generated TypeScript are inferred from keys missing in some records of your XML, following TypeScript Handbook. Include the optional fields in your sample so they are typed correctly.
XML (eXtensible Markup Language) (XML) — XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. TypeScript interfaces (TypeScript) — TypeScript interfaces give compile-time types for data crossing your app. This converter maps the structure of your XML onto TypeScript so you can use it for typed API clients.
Yes. Invalid XML is flagged with a clear error before anything is converted. Common XML problems to check are matched start and end tags, a single root element, and quoted attribute values. Starting from clean input keeps the generated TypeScript accurate.
Yes. The entire XML-to-TypeScript conversion runs locally in your browser in JavaScript — your XML is never uploaded, logged or stored. That matters when the data is something like SOAP web services, which should not leave your machine.
The generated TypeScript is ready for typed API clients, React/Next.js props and shared front/back types. Copy or download it and drop it straight into your codebase.
