XML to Ruby Converter

Working with XML data and need Ruby models fast? XML supports both element content and attributes — this converter handles both when generating typed models. This free, browser-based converter parses your XML and generates clean, production-ready Ruby code — no account required.

Generate Ruby Struct or plain Ruby classes with attribute accessors for clean JSON parsing.

How to use this converter

  1. Paste your XML into the left editor panel
  2. Click Generate
  3. Copy the generated Ruby code from the right panel

No account. No upload. No tracking. Runs entirely in your browser.

Example Ruby output

class Address
  attr_accessor :city, :zip
 
  def initialize(data = {})
    @city = data['city']
    @zip  = data['zip']
  end
end
 
class User
  attr_accessor :id, :name, :email, :address
 
  def initialize(data = {})
    @id      = data['id']
    @name    = data['name']
    @email   = data['email']
    @address = Address.new(data['address'] || {})
  end
end

Why automate XML-to-Ruby conversion?

Writing Ruby Struct / class definitions by hand from XML is:

  • Tedious — especially for deeply nested or large XML payloads
  • Inconsistent — naming conventions drift when done manually across a team
  • Fragile — when the XML schema changes, hand-written models lag behind

Ruby's Struct provides a concise way to define value objects with automatic accessors — ideal for lightweight data containers.

This converter handles all of that automatically, giving you idiomatic Ruby code that matches your XML structure exactly.

Ruby and XML: what you need to know

Ruby is a dynamically typed, expressive OOP language, widely used in Rails applications and rapid prototyping. It uses Struct or plain class with attribute accessors for structured data — making it a natural fit for XML-driven applications.

What the converter generates

Output produces Ruby classes using attr_accessor declarations with an initialize method and a from_hash class method for easy JSON deserialization. Follows Ruby naming conventions with snake_case attributes.

A common gotcha

Ruby has no static types — consider adding Sorbet or RBS type annotations if you need type checking in larger codebases.

XML input characteristics

XML allows mixed content (text + child elements), namespaces, and CDATA sections — more expressive but more verbose than JSON. XML is the foundation of many enterprise integration standards including XSLT, XSD, and SOAP.

When should I use this converter?

Use this when building Rails APIs or Ruby scripts that consume external JSON/XML/YAML payloads and you want explicit typed models rather than raw hash access.

Common use cases

  • Generating Ruby models for Rails API controllers consuming external services
  • Creating typed structs for Faraday or HTTParty API client wrappers
  • Producing model classes for Sidekiq workers that process JSON job payloads
  • Generating Ruby models from Rails backends API responses
  • Creating typed DTOs for scripting
  • Rapid prototyping with real XML payloads
  • Keeping Ruby structs in sync when XML schemas evolve
  • Onboarding new team members by auto-generating the data layer
  • Validating XML contract compatibility with Ruby type definitions

Frequently asked questions

Does this converter support eXtensible Markup Language namespaces and nested structures?

Yes. XML supports both element content and attributes — this converter handles both when generating typed models. The parser handles deeply nested structures and generates matching nested Ruby Struct / class definitions.

How are optional fields handled in the Ruby output?

Fields that may be absent or null in your XML are marked as optional in the generated Ruby code. Note: Ruby has no static types — consider adding Sorbet or RBS type annotations if you need type checking in larger codebases.

Can I use the output directly in a Rails backends project?

Yes. The generated Ruby code follows idiomatic patterns for Rails backends — you can copy it directly into your project.

Does this work for large XML payloads?

Yes. The converter is optimized for large and deeply nested XML structures, running entirely in the browser without page reloads or server round-trips.
