How do I convert a YAML file to RB?

Paste your YAML content into the input area or upload a .yml file. Select 'RB' as the target format and click 'Convert.' The tool outputs a Ruby script with the same data structure, using proper Ruby syntax for hashes, arrays, and scalars. You can download the resulting .rb file.

Why convert YAML to Ruby (RB)?

YAML is plain data, while RB is executable Ruby code. Converting YAML to RB lets you embed configuration directly into Ruby applications, removing the need to parse YAML at runtime. This improves load performance, eliminates YAML dependency, and enables dynamic Ruby logic such as defaults, conditionals, and method calls inside your configuration.

How does the YAML to RB converter handle anchors, aliases, and custom tags?

The converter resolves YAML anchors and aliases by expanding them into independent Ruby objects, so repeated data becomes duplicated but safe for manipulation. Custom YAML tags (e.g., !ruby/object) are not supported and will be skipped or converted to strings. Multi-line strings are preserved using Ruby heredoc syntax when necessary, and comments are stripped unless they are part of the scalar.

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

Does this converter work on mobile phones and tablets?

Yes! YAML-TO-RB works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
