Text Case Converter

Paste any text and switch it between common cases with one click — UPPERCASE and lowercase for basic formatting, Title Case and Sentence case for headings and prose, and camelCase or snake_case for variable and file naming in code.

This is a common small task in both writing and programming — cleaning up text pasted from somewhere else, or converting a phrase into a valid variable name — that's tedious to do by hand for anything longer than a few words.
