Questions & Answers
Sentence Case is a capitalization style where only the first letter of the first word of each sentence is capitalized, while all other words remain lowercase, except when language rules require the use of uppercase letters, such as for proper nouns, acronyms, and abbreviations. This format is the standard used in running text, emails, documents, articles, and most written content, providing a more natural and consistent reading experience.
No. Since proper nouns, acronyms, and other words that should remain capitalized are also converted to lowercase, it is recommended to review the result before using it.
Only the period (.), the exclamation mark (!) and the question mark (?). A line break on its own does not produce a capital letter, and the dot in an abbreviation such as 'etc.' is read as the end of a sentence, so those are two things worth checking in the converted text.
Use Sentence Case for running text, emails, articles and body copy, where only the first letter of each sentence is capitalized. Use Title Case for headlines and headings, where every main word starts with a capital letter. For that, use the Title Case Converter.
