What is JSON to Ruby Converter?
Need to generate Ruby classes from your JSON (JavaScript Object Notation) data? This tool does that instantly. Perfect for Ruby developers working with Rails, Sinatra, or Ruby scripts who need to deserialize JSON into strongly-typed Ruby objects. Generate classes, attributes, and type definitions automatically.
According to Ruby documentation, classes and attributes make code more maintainable. Our converter analyzes your JSON structure and generates proper Ruby classes. First, validate your JSON using our JSON Validator, then convert it to Ruby. You can also format your JSON with our JSON Formatter first if needed.
Everything happens in your browser – your JSON never leaves your computer. Convert, download, and use your Ruby classes right away.
What Makes This Tool Different
Automatic Class Generation
We analyze your JSON structure and automatically generate Ruby classes. JSON objects become classes, arrays become arrays, everything gets proper Ruby syntax.
Attr Accessor Support
Generate Ruby classes with attr_accessor for cleaner code. Automatic getters and setters make working with JSON data easier.
Nested Structure Support
Handles deeply nested JSON structures perfectly. Nested objects become nested classes, arrays become arrays with proper Ruby syntax.
File Upload Support
Got a big file? Just upload it. Works great for converting those massive JSON configs or data files without copy-pasting.
Download Ruby
One click to download your Ruby file. Drop it into your Ruby project and start using it. Perfect for Rails, Sinatra, or Ruby scripts.
Clean Code Output
The generated Ruby code is clean and well-formatted. Classes are properly named, attributes are structured correctly, and the code follows Ruby conventions.
How It Works
Paste or Upload JSON
Paste your JSON into the left editor, or click "Upload" to load a file. The JSON should be valid – use our JSON Validator first if you're not sure. You can also click "Sample" to see an example.
Configure Options
Set your class name, package name, and choose whether to use attr_accessor. These settings customize the generated Ruby code to match your project's conventions.
Download or Copy
Click "Download" to save the Ruby file, or "Copy" to copy it to your clipboard. The Ruby code is ready to use in your project. Drop it into your Ruby project and start using it.
When You'd Actually Use This
Rails Applications
Generate Ruby classes from JSON API responses for Rails. Create models or data structures for JSON-based APIs or configuration files. Perfect for Rails' JSON processing needs.
Sinatra Applications
Create Ruby classes from JSON data for Sinatra apps. Generate data models for JSON-based APIs or integrations. Perfect for Sinatra's flexible architecture.
Ruby Scripts
Generate Ruby classes from JSON data for Ruby scripts. Create data models for JSON-based data processing or automation. Perfect for Ruby scripting needs.
Code Generation
Generate Ruby code from JSON data structures. Perfect for creating data models, DTOs, or entity classes from JSON schemas or API responses.
Common Questions
Is my JSON data stored?
Nope. Everything happens right in your browser. Your JSON never leaves your computer – we don't even see it.
How are JSON objects handled?
JSON objects become Ruby classes. Properties become class attributes, and nested objects become nested classes or references. Arrays become Ruby arrays.
Can I use the generated Ruby code?
Yes. The generated Ruby code is valid and ready to use. Drop it into your Ruby project and start using it. You may want to review and refine the classes for your specific use case.
What about JSON parsing libraries?
The generated Ruby classes work with Ruby's built-in JSON library. You can use JSON.parse to convert JSON strings into these Ruby objects.
Does it work with large JSON files?
Yep. Since everything happens in your browser, it depends on your device. Small to medium JSON structures convert instantly. Really huge structures might take a few seconds.
What Ruby version is supported?
The generated code works with Ruby 2.0 and later. It uses standard Ruby features and follows Ruby conventions for maximum compatibility.
Other JSON Tools You Might Need
Conversion is just one JSON task. Here are other tools that work well together:
