How It Works & Underlying Concept

Text case formatting transforms strings to match programming conventions (such as camelCase in JavaScript, snake_case in Python, kebab-case in CSS and URLs) or typographic styles (such as Title Case for headlines and Sentence case for body copy).

Mathematical Formula / RuleCase transformations apply regex word boundary matching and capitalization maps.
