Converts any text to eight common case styles: UPPERCASE, lowercase, Title Case (capitalize each word), Sentence case (capitalize after . ! ?), plus the developer naming conventions camelCase, PascalCase, snake_case and kebab-case. The naming styles split words on spaces, hyphens and underscores and are applied line by line, so you can convert a whole list of identifiers at once.
Handy for renaming variables, database columns, CSS classes, file names or cleaning up headlines. Everything runs locally in your browser — nothing is uploaded to any server.
