Ruby Hash to JSON Converter
This tool helps developers quickly convert Ruby Hashes (including rocket syntax
:key => value and symbol syntax key: value) into valid JSON objects.
It also works in reverse, converting standard JSON into Ruby Hash syntax.
It handles common Ruby types like nil (converting to null) and
recognizes both string and symbol keys.
Why use this converter?
- Safe & Client-Side: All data is processed in your browser. No data is sent to any server.
- Bidirectional: Switch easily between parsing Ruby output logs and generating Ruby config files from JSON.
- Syntax Aware: Supports legacy Ruby rocket syntax and modern JSON-style Ruby hashes.
Common Use Cases
- API Testing: Convert Ruby API responses to JSON for testing
- Configuration Files: Transform JSON configs to Ruby hash format
- Data Migration: Migrate between Ruby and JavaScript data structures
- Log Parsing: Parse Ruby debug output and convert to JSON
Syntax Examples
{:name => "John", :age => 30}
Ruby Symbol Syntax:
{name: "John", age: 30}
JSON:
{"name": "John", "age": 30}
Frequently Asked Questions
Can it ignore comments in Ruby hash?
Currently, this is a heuristic converter. It might fail on complex Ruby code with comments. Please ensure the input is a valid Ruby Hash structure.
How are symbols handled?
Ruby symbols (e.g., :status) are converted to JSON strings (e.g.,
"status") as JSON does not have a symbol type.
What about nested structures?
This converter handles nested hashes and arrays. Both Ruby and JSON support arbitrary nesting, which is preserved during conversion.
Can I convert Ruby classes or objects?
No, this tool only converts basic Ruby data structures (Hash, Array, String, Number, Boolean, nil). Custom Ruby classes and objects are not supported.
