Sentence case suits most headings, buttons and emails, and is easier to read. Title case is common for book, film and song titles. Upper case works for short labels and acronyms, but long passages in capitals are harder to read and can come across as shouting. Lower case is handy for tidying text before reformatting it.
Paste the text in, choose sentence case, then check any names, places and acronyms by hand.
Sentence case capitalises only the first letter of each sentence and proper nouns, like normal writing. It's the style GOV.UK and many UK publishers use for headings.
Title case capitalises the main words of a title. Short words such as 'and', 'of' and 'the' stay lower case unless they come first.
Sentence case and lower case can't tell which words are proper nouns, so check names and places afterwards.
