Case Converter

Type anything and get it back in every naming style at once. The splitter reads camelCase, snake_case, kebab-case, RUN-ON CAPS and plain spaces, so you can pour one form in and take any other form out. Tap or hover a word below to see where it lands in each line.

Every case

joined as one name words glued together, punctuation dropped
left as a sentence commas, apostrophes and question marks stay put — only the capitals move (run-together names get spaced out first)

Sentence case can’t know your proper nouns, so it lowers everything except the start of a sentence — but it keeps run-on capitals like AM and mixed spellings like iPhone exactly as you typed them. Title Case leaves the little words (a, of, at, the) lowercase unless they start or end the line.
