Which case goes where

camelCase: JavaScript/Java variables and functions. PascalCase: class names in most languages, React components, C# methods. snake_case: Python variables and functions, SQL columns, Rust. kebab-case: URLs, CSS classes, HTML attributes, CLI flags. CONSTANT_CASE: constants and environment variables everywhere.

How the converter splits words

The tool detects word boundaries from spaces, underscores, hyphens, and capital-letter transitions, so it can convert from any convention to any other — paste getUserById and get snake_case get_user_by_id back.
