Which cases can I convert to?

Common options include UPPERCASE, lowercase, Title Case, and Sentence case, plus programmer-friendly formats like camelCase, PascalCase, snake_case, and kebab-case.

Title Case capitalizes the first letter of each significant word, while Sentence case only capitalizes the first letter of the sentence. Both are one click away.
