How do I convert a JSON file to a Ruby (RB) file?

Paste your JSON into the converter, click 'Convert', and the tool generates a .rb file containing a Ruby hash. You can copy the code or download the file. The process takes under a second and preserves the structure exactly.

Why convert JSON to Ruby instead of parsing JSON at runtime?

Converting JSON to Ruby code lets you use data as static literals, which avoids runtime parse errors, improves startup speed, and lets you use Ruby-specific features like symbols and comments. It's ideal for configuration files, test fixtures, and generated code.

How does the JSON to RB converter handle null, booleans, and Unicode characters?

JSON null becomes Ruby nil, booleans map to true/false, and numbers remain numeric literals. Strings are escaped for Ruby, including quotes, backslashes, and newlines. Unicode characters are preserved in UTF-8, so the resulting Ruby hash is fully equivalent to the original JSON data.

Yes, JSON-TO-RB on LetsConvert is 100% free with no registration or hidden fees required.
