How to convert text to sentence case
- Paste text that is in capitals, has random capitals, or has no capitals at all.
- Press the highlighted Sentence case button: each sentence starts with a capital letter and the rest is lowercase.
- Copy it and check names and acronyms, which should keep their capitals.
What sentence case is
Sentence case is the normal way of writing prose: a capital letter at the start of each sentence, after a full stop, question mark or exclamation mark, and lowercase elsewhere, apart from proper nouns. It is the easiest style to read, and many organisations, including the UK government's GOV.UK, Google and Microsoft, use it for headings and buttons as well as body text.
The converter is ideal for fixing text that was typed with Caps Lock on, pasted from an old system that stored everything in capitals, or written quickly on a phone with no capitals at all. It also capitalises a standalone "i". It cannot know which words are names, so "london" stays lowercase; give the result a quick read and fix proper nouns by hand.
