Frequently asked questions
Does my text get uploaded anywhere?
No. Case Converter runs entirely in your browser — your text is never sent to a server.
How does camelCase, snake_case and kebab-case handle spaces and punctuation?
Words are detected by splitting on spaces, punctuation and camelCase boundaries, then rejoined using the target convention's separator (none for camelCase, underscore for snake_case, hyphen for kebab-case).
What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word. Sentence case capitalizes only the first letter of each sentence, like normal prose.
