How to Convert Ruby to JSON - Step by Step Guide

Step 1

Input Your Ruby Code

Start by pasting your Ruby hash, array, or data structure that needs to be converted to JSON format. The tool supports both old (=>) and new (:) hash syntax.

•
Paste Ruby code: Copy your Ruby hash or array directly into the editor
•
Upload a file: Load Ruby code from a .rb file on your computer
•
Try samples: Click sample buttons to see different Ruby patterns (hashes, symbols, nested structures)

Example: Ruby Hash

Here's a typical Ruby hash:

{
  name: 'Chris Taylor',
  age: 29,
  is_active: true,
  skills: ['Ruby', 'Rails', 'PostgreSQL']
}
Step 2

Click Convert Button

Click the green "Convert" button to send your Ruby code to our Python backend API for processing. The converter transforms Ruby syntax to JSON format, handling true/false, nil values, symbols, and proper quote formatting.

•
Boolean conversion: Ruby true/false becomes JSON true/false
•
Nil handling: Ruby nil converts to JSON null
•
Hash support: Ruby hashes ( or =>) convert to JSON objects
•
Symbol conversion: Ruby symbols (:symbol) convert to JSON strings
•
Nested structures: Handle complex Ruby hash and array hierarchies

Example: Converted JSON Output

The same data in JSON format:

{
  "name": "Chris Taylor",
  "age": 29,
  "is_active": true,
  "skills": [
    "Ruby",
    "Rails",
    "PostgreSQL"
  ]
}
Step 3

Get Valid JSON Output

The tool produces properly formatted, valid JSON that's ready to use in your applications, APIs, or configurations.

•
Real-time validation: Green checkmark confirms your JSON is syntactically correct
•
Proper formatting: Beautified with correct indentation and structure
•
Ready for APIs: Use directly in REST API responses or database storage
Step 4

Copy or Download JSON

Copy the JSON to your clipboard or download it as a .json file for use in your Ruby or Rails projects.

•
Copy to clipboard for immediate use
•
Download .json file for integration into your codebase
•
Use in Rails: Perfect for config files and API responses
•
Export options: Convert to readable tables or minify for production

What is Ruby to JSON Conversion?

Ruby to JSON conversion transforms Ruby data structures like hashes, arrays, and symbols into standard JSON format. This process converts Ruby-specific syntax (=>, :symbols) into JSON-compliant syntax for data interchange and API communication.

The conversion is essential for Ruby and Rails applications, REST APIs, and configuration management where JSON is the standard format for data exchange. You can also convert other languages like Python to JSON or PHP to JSON using our related tools.

Frequently Asked Questions

How do I convert Ruby hash to JSON?

Simply paste your Ruby hash into the converter. It will automatically convert Ruby syntax (=>, :, true, false, nil) to valid JSON format. The output can then be formatted or minified based on your needs.

Does the converter handle nested Ruby hashes?

Yes! The converter properly handles nested hashes, arrays, and mixed data structures, converting them to equivalent JSON representations while maintaining the structure. You can also convert the reverse direction using our JSON to Ruby converter.

What Ruby data types are supported?

The converter supports Ruby hashes (both => and : syntax), arrays, symbols, strings, numbers, booleans (true/false), and nil. These are converted to their JSON equivalents: objects, arrays, strings, numbers, booleans, and null.

Is the output valid JSON?

Yes! The converter produces standard, valid JSON that can be used in any application or API. The output is properly formatted and validated. You can further validate the JSON or convert it to other formats like TypeScript or Python.

Is the Ruby to JSON converter free?

Yes, completely free with no limitations on data size or conversion frequency. No registration required. Check out our other free tools like JSON formatter, JSON validator, and JSON to Table converter.
