Title Case vs Capitalized Words
Capitalized Words starts every word with a capital letter. Title Case follows common headline style: short articles, conjunctions and prepositions such as a, and, of and in stay lowercase unless they are the first or last word. Style guides differ on details, so give important headlines a final read.
Sentence case
Everything becomes lowercase, then the first letter of each sentence and each new line is capitalized. Proper nouns such as names and places will need a quick manual fix.
