About this tool
Word-based cases (camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE) split the input on spaces, punctuation, and existing case boundaries — so pasting some-existing_slug or anExistingCamelName still splits into sensible words rather than treating them as one token. Title Case here simply capitalizes every word; it doesn't apply style-guide rules about which short words (like "of" or "the") stay lowercase, since those rules vary by publication.
Sentence case capitalizes the first letter after a period, question mark, or exclamation point, in addition to the very first letter of the text. Nothing you paste here is sent to a server — the entire tool runs as JavaScript in your browser tab.
