Choose the right case

Title case capitalizes every word, including short words. Sentence case lowercases the text before capitalizing sentence starts, so check names and acronyms. Identifier styles split spaces, punctuation and existing camelCase boundaries. They retain Unicode letters and numbers and do not guarantee a valid identifier in every programming language.

Line-based editing normalizes Windows and older Mac line endings to LF. Keep your original if line-ending style matters.
