What is the Sentence Case Converter?
The Sentence Case Converter formats text the way normal sentences are written — with a capital letter at the start of each sentence and lowercase letters everywhere else. It's ideal for cleaning up text that was typed in all caps or with inconsistent capitalization.
How Does It Work?
Paste your text into the input field and click "Convert." The tool first lowercases the entire text, then capitalizes the first letter of the text and the first letter following each sentence-ending punctuation mark (like a period, exclamation point, or question mark).
