100% Client-Side

Your code stays in your browser. Safe for proprietary Ruby on Rails applications.

How this Ruby Formatter works

This code beautifier reformats Ruby source files with proper indentation, spacing, and style conventions following Ruby community guidelines. The parser recognizes Ruby syntax including class/module definitions, method blocks, control structures, and iterators, applying consistent 2-space indentation (or 4-space optionally).

Hash rocket conversion transforms legacy :symbol => value syntax to modern key: value notation for cleaner code. Space normalization adds consistent whitespace around operators and after commas. Method separation inserts blank lines between def...end blocks improving visual structure.

The formatter preserves string literals, heredocs, regex patterns, and comments exactly while restructuring surrounding code. Upload or paste Ruby files, preview formatted output, then copy or download results. All processing executes locally—proprietary Rails applications and gems remain private.

Frequently Asked Questions

Does this follow Ruby style guidelines?

Yes! The formatter follows Ruby community conventions including 2-space indentation (configurable), proper spacing, and consistent hash syntax.

What is the hash rocket conversion?

Ruby has two hash syntaxes: :key => value (hash rocket) and key: value (new syntax). Enabling conversion changes the old style to the modern style.

Does it preserve my comments?

Yes. Comments are preserved during formatting. String literals, heredocs, and regex patterns are also kept intact.

Is 2-space or 4-space indentation standard?

2-space indentation is the Ruby community standard. However, 4-space is available for projects that require it.

Is my code secure?

Yes. All formatting runs locally in your browser. Your code never leaves your device, making it safe for proprietary Ruby projects.
