Frequently asked questions
- Will converting case change my punctuation?
- No. Only letter casing changes — spacing, punctuation and line breaks stay exactly as you pasted them.
- What is sentence case?
- Sentence case capitalises the first letter after every full stop, question mark or exclamation mark and lowercases the rest.
