Convert XML to Ruby online, free. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. Ruby keyword-init Structs give lightweight, typed-by-convention value objects. XML to Ruby 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 Ruby types following the Ruby Struct 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 Rails & Sinatra apps, API response objects and config and DTOs.
It maps the full structure of your XML onto idiomatic Ruby types, following the Ruby Struct 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 Ruby types from Ruby 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 Ruby, 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 Ruby equivalent:
XML input:
<product>
<sku>A-100</sku>
<price>19.99</price>
<active>true</active>
</product>Output:
Product = Struct.new(:sku, :price, :active, keyword_init: true)Paste your XML into the editor and press "Convert to Ruby". The tool parses it against the W3C XML 1.0 grammar, then generates Ruby types following Ruby Struct 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 Ruby, attributes and element text become fields, and values stay strings unless Ruby coerces them — so review numeric or boolean fields after converting.
Optional or nullable members in the generated Ruby are inferred from keys missing in some records of your XML, following Ruby Struct. 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. Ruby structs (Ruby) — Ruby keyword-init Structs give lightweight, typed-by-convention value objects. This converter maps the structure of your XML onto Ruby so you can use it for Rails & Sinatra apps.
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 Ruby accurate.
Yes. The entire XML-to-Ruby 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 Ruby is ready for Rails & Sinatra apps, API response objects and config and DTOs. Copy or download it and drop it straight into your codebase.
