This tool transforms JSON into clean, idiomatic Ruby classes (Plain Old Ruby Objects). It handles nested structures by creating multiple classes and uses standard Ruby types for data mapping, ensuring your Ruby models are a direct and accurate reflection of your JSON data. It is perfect for Ruby on Rails developers or anyone working with Ruby for data processing, web scraping, and API integration. The tool provides a convenient way to encapsulate behavior and data validation for your incoming payloads, promoting better object-oriented design in your Ruby applications.

Input your JSON to generate Ruby classes or Structs. It handles nested data by creating multiple classes or nested hashes.

Manually defining Ruby classes and attribute accessors for large and nested JSON responses can be highly repetitive and time-consuming. This tool automates the task, providing you with a solid, well-organized starting point for your Ruby models and allowing you to focus on the core business logic of your application.

Example Input

{
  "id": 1,
  "name": "John Doe",
  "email": "john@example.com",
  "isActive": true,
  "tags": ["admin", "dev"],
  "profile": {
    "bio": "Software Engineer",
    "skills": ["Go", "React", "TypeScript"]
  }
}

Example Output

class User
  attr_accessor :id, :name, :email, :isActive
end

Naming Conventions

Fix: Ruby uses snake_case. The tool automatically converts camelCase JSON keys to snake_case for Ruby attributes.

Does it support Struct?

Yes, you can choose to generate Ruby `Struct` for simple, immutable data models.
