Questions about Sentence case
More answers in the TextVix FAQ.
Are proper nouns kept capitalized?
No — sentence case lowercases everything except the first letter of each sentence and “I”. Check names afterwards.
Does it handle abbreviations like “e.g.”?
Yes. Common abbreviations such as i.e., e.g., Mr. and Dr. don’t start a new sentence.
Is my text uploaded anywhere?
