Case Converter — FAQ
What is the difference between camelCase and snake_case?
Both join words without spaces. camelCase capitalises each word after the first and uses no separator, while snake_case keeps words lowercase and joins them with underscores.
Does the converter handle several lines?
Yes. UPPERCASE, lowercase, Title Case and Sentence case keep your line breaks, and the code-style options convert each line on its own.
Why does Sentence case lowercase names?
This tool lowercases everything except the first letter of each sentence, so proper nouns need to be capitalised again by hand.
