Converting text case means changing the capitalization pattern without changing the actual words. UPPERCASE converts every letter to capital, lowercase converts every letter to small, Title Case capitalizes the first letter of every word (commonly used for headings and names), and Sentence case capitalizes only the first letter of each sentence, matching normal written English.
Title case is typically used for headlines, book titles, and proper names. Sentence case is standard for body text and most everyday writing. UPPERCASE is often used for emphasis, acronyms, or legal disclaimers, while lowercase is sometimes used stylistically in usernames, hashtags, or casual branding.
Converting 'the great gatsby' to Title Case gives 'The Great Gatsby', each word's first letter is capitalized and the rest lowercased. Converting 'hello world. how ARE you?' to Sentence case instead gives 'Hello world. How are you?', only the first letter of each sentence is capitalized, and any existing unusual capitalization mid-sentence (like 'ARE') is normalized to lowercase.
Expecting Title Case to know which small words (like 'of', 'the', 'and') should stay lowercase in formal titles, this tool capitalizes every word's first letter uniformly, some style guides prefer lowercase for minor words, which would need manual adjustment afterward.
Assuming Sentence case preserves intentional mid-sentence capitalization, like an acronym or a proper noun, it lowercases everything except sentence-starting letters, so 'NASA' would need to be manually re-capitalized after converting.
Applying UPPERCASE to large blocks of body text for emphasis, in most style contexts, all-caps for long stretches of text is harder to read and can come across as shouting rather than emphasis.
Title Case capitalizes the first letter of every word, commonly used for headings and titles.
Sentence case capitalizes only the first letter of each sentence, similar to normal written English.
