Different languages and ecosystems each settled on their own convention — converting between them by hand is fiddly and error-prone.
Programming languages each picked their own naming convention: JavaScript and Java lean on camelCase, classes and React components use PascalCase, Python and Ruby prefer snake_case, CSS and URLs favour kebab-case, and constants are usually CONSTANT_CASE. Prose has its own rules — Title Case for headings, Sentence case for everything else.
Paste any text and it's split into words — handling existing camelCase, snake_case, hyphens, spaces and punctuation — then rebuilt into each style. lowercase, UPPERCASE and Sentence case keep your original spacing and just change the letters. Everything runs in your browser; nothing is sent anywhere. Click any variant to copy it.
