Questions
What is sentence case?
Writing where only the first word of a sentence and proper nouns start with a capital, as in this answer. Many style guides, including GOV.UK and Microsoft, prefer it for headings and buttons.
Will it keep names capitalised?
No tool can know every name. Check proper nouns like people, places and brands after converting.
Sentence case or title case for headings?
AP and Chicago use title case for headlines; APA uses sentence case for reference titles. Pick one and use it consistently.
