FAQ
Which words stay lower case in Title Case?
Articles, short conjunctions and short prepositions such as a, an, the, and, but, of, in, on, to and vs — unless they start or end the title or follow a colon.
Can I convert many variable names at once?
Yes. camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case convert each line separately, so paste one name per line.
Will it break acronyms like NASA or brand names like iPhone?
Title Case keeps words that are already all-caps or mixed-case as they are, unless your whole input is in capitals.
