How do I convert a Ruby Hash to JSON?

Simply paste your Ruby Hash (e.g., {:name => "John"}) into the left panel and click 'Ruby -> JSON'. Our tool handles rocket syntax (=>), symbols (:key), and nil values automatically.

Can I convert JSON back to Ruby?

Yes! Paste valid JSON into the right panel and click 'JSON -> Ruby'. You can choose between modern syntax (key:) or traditional rocket syntax (key => value) for the output.

How does this tool handle 'nil'?

Ruby's 'nil' is converted to JSON 'null', and vice-versa. This ensures data compatibility between the two formats.

Are symbols supported?

Yes, Ruby symbols (e.g., :status) are converted to JSON strings (e.g., "status"). When converting back to Ruby, you can typically choose to keep them as strings or convert keys to symbols depending on your preference.

Absolutely. All conversion happens locally in your browser using JavaScript. No data is sent to any server.

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.

FAQs

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.
