Capitalizing text commonly makes it easier to read and helps readers keep track of what’s important. Uppercase letters are often used for acronyms, abbreviations, and other words that would be difficult to read if they were not capitalized.
Title case is used to capitalize the first letter of each word except articles (the and a/an), conjunctions, and prepositions. Sentence case only capitalizes the first letter of sentences or proper nouns.
The benefits of case conversion are that it makes the text easy to read, search for, and share.
