Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every major word ("The Quick Brown Fox"), while Sentence case only capitalises the first letter of each sentence ("The quick brown fox.").
What is camelCase?
camelCase joins words without spaces and capitalises every word except the first, e.g. "userFirstName". PascalCase also capitalises the first word: "UserFirstName".
Does the converter keep line breaks?
Yes for text styles such as upper, lower, title and sentence case. Identifier styles like camelCase are applied to each line separately.
