JSON to Ruby Class

Tool Introduction

The JSON to Ruby Class tool is an efficient and practical online converter designed to help developers quickly convert JSON (JavaScript Object Notation) data structures into corresponding Ruby class definitions. There's no need to manually write tedious class and attribute code; simply paste your JSON data into the "JSON String" input box, and the tool will automatically generate a standardized Ruby class file, displayed in the "Converted Class" output box. This greatly improves development efficiency and reduces errors that might occur from manual writing. This tool supports converting complex nested JSON structures into multi-level Ruby classes, perfectly meeting data model mapping requirements.

How to Use

1. Paste the JSON data you want to convert into the "JSON String" input box on the left. Please ensure the pasted JSON string is valid and correctly formatted.
2. The tool will automatically parse the JSON structure and generate corresponding Ruby class code based on its content.
3. The conversion result will be displayed in real-time in the "Converted Class" output box on the right.
4. You can directly copy the generated Ruby class code and integrate it into your Ruby project.

Input Parameter Description: The "JSON String" is required to be valid data conforming to JSON syntax specifications, which can be a JSON object or a JSON array.

Output Format Description: The "Converted Class" will be presented in the form of class definition code conforming to Ruby syntax specifications, typically including class name, attributes (attr_accessor), and initialization methods (initialize), etc.

Frequently Asked Questions

• Q: What input formats does this tool support?
• A: This tool only supports standard JSON format data as input, including JSON objects ({}) and JSON arrays ([]). Please ensure the input JSON string has correct syntax.
• Q: What are the characteristics of the output Ruby class code?
• A: The generated Ruby class code typically creates an attr_accessor for each JSON attribute and provides an initialize method for easy object initialization from a Hash. For nested JSON objects, the tool will attempt to generate independent nested Ruby classes.
• Q: How does the tool handle camelCase in JSON?
• A: When generating Ruby classes, the tool will usually automatically convert camelCase in JSON attribute names to the conventional Ruby snake_case, for example, productName will be converted to product_name.
• Q: If JSON contains arrays, how are they represented in Ruby classes?
• A: Arrays in JSON will be directly mapped to Ruby's Array type. If array elements are complex JSON objects, the tool may generate corresponding Ruby class arrays.

Notes

• Please ensure that the input "JSON String" is valid data that fully complies with JSON syntax specifications, otherwise, it may lead to conversion failure or the generation of incorrect Ruby code.
• Complex nested JSON structures may generate multiple associated Ruby classes. Please pay attention to the generated code structure and the relationships between classes.
• The tool intelligently infers data types and naming, but for some special or ambiguous JSON structures, users may need to manually adjust and refine the generated Ruby code according to actual business logic.
• The generated Ruby class code is only a skeleton of the data model; you may need to add more methods, validation logic, or integrate ORM (such as ActiveRecord) according to project requirements.
