Case converter

Convert between every case a codebase or a document needs, all at once so you can pick the one you wanted. The word splitter handles the awkward part properly: HTTPServer is two words, not one, and not five.

Runs entirely in this tab. What you paste is never sent anywhere.
Text

The word splitter handles acronyms the way you would expect: HTTPServer is two words, so it becomes http_server rather than h_t_t_p_server.
