When each case is the right one
Sentence case is the default for prose, and increasingly for headlines too — most publications and product interfaces have moved to it because it reads faster.
Title Case belongs to book, film and article titles, and to publications whose style guide calls for it. The rule about short words is what separates it from simply capitalising everything.
UPPERCASE is for acronyms, and for emphasis in small doses. A whole paragraph of capitals is measurably slower to read, because the shapes of the words disappear.
lowercase suits hashtags, usernames, email addresses and anywhere case carries no meaning.
Fixing text that arrived in the wrong case
The common problem is a block of text typed with Caps Lock on. Converting it straight to lowercase loses the capital letters that should have stayed, so convert toSentence case instead: each sentence gets its capital back, and a standalone “I” is restored. Proper nouns still need a manual pass — no tool can know that “paris” is a city and not your dog.
If the text also arrived with double spaces or stray line breaks, run it through thetext cleaner first.
