What is sentence case?

Sentence case is how normal text is written: the first letter of each sentence is a capital and the rest is lowercase. The converter starts a new sentence after a period, question mark, exclamation mark or line break.

Example

Before

THANKS FOR YOUR ORDER. IT WILL SHIP TOMORROW! ANY QUESTIONS? JUST REPLY.

After

Thanks for your order. It will ship tomorrow! Any questions? Just reply.

When to use sentence case

Use it for paragraphs, emails, product descriptions, captions, and for titles in French, Spanish or Portuguese, which only capitalize the first word. Many design systems also use sentence case for buttons and menus.

Frequently Asked Questions

Will names keep their capital letters?

No. Sentence case cannot know which words are names, so proper nouns (Paris, Maria, iPhone) become lowercase unless they start a sentence. Check them after converting.

How is a new sentence detected?

After a period, an exclamation mark or a question mark followed by a space, and at the start of every new line.

Is sentence case used for titles?

Yes, in many languages and in some English style guides. For English headlines, Title Case is more common.
