When you need to map JSON data from an API response to Ruby objects, manually writing the corresponding class definitions is tedious and error-prone. This tool parses your input JSON string and automatically generates standard Ruby class code based on its key-value structure. The output typically includes a class name, attr_accessor property definitions, and an initialize method that accepts a hash, enabling a quick conversion from a JSON data structure to a Ruby object model.
userName) to Ruby's conventional snake_case (user_name).attr_accessor and an initialize method, ready to be copied and used.How are array types handled when converting JSON to a Ruby class?
Arrays in JSON are directly mapped to Ruby's Array type. For example, "tags": ["ruby", "json"] in JSON will generate attr_accessor :tags, which will be of type Array.
How can I quickly convert JSON to a Ruby class?
Simply paste your JSON, and the tool will automatically generate the class. The core steps are: prepare valid JSON -> paste it into this tool -> copy the generated Ruby class code. The key is that the input JSON must be syntactically correct.
Please ensure the input JSON string is syntactically correct; otherwise, the conversion will fail. The generated code is a basic data model boilerplate. You may need to add validations, serialization methods, or integrate it with an ORM framework like ActiveRecord based on your business logic. For extremely complex or non-standard JSON structures, the generated result may require manual adjustments to class names or property relationships.
We recommend using this tool when receiving data from external APIs or defining internal data contracts. The generated class can be conveniently used with JSON.parse: data = JSON.parse(response_body, object_class: YourGeneratedClass). For common data exchange scenarios, such as {"user": {"name": "John", "age": 30}}, the tool will generate a User class with attr_accessor :name, :age, allowing you to instantiate objects directly with User.new(name: 'John', age: 30), significantly improving development efficiency.
