Convert XML to Pydantic online, free. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. Pydantic BaseModels validate and parse data into typed Python objects. XML to Pydantic 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 Pydantic types as Pydantic BaseModel classes with typed fields following the Pydantic 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 FastAPI request/response models, settings validation and ETL parsing.
It maps the full structure of your XML onto idiomatic Pydantic types, following the Pydantic 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 Pydantic types from Pydantic 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 Pydantic, 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.
