What is a case converter?

A case converter changes the capitalization of text. You paste a block of words, pick a style, and get the same text rewritten in a new case. It's useful for cleaning up messy copy, formatting code identifiers, fixing accidentally caps-locked sentences, or just having a bit of fun with aLtErNaTiNg cAsE.
