About Sentence case Converter
Text pasted from spreadsheets or shouted in all caps often needs proper sentence casing. This tool lowercases everything, then capitalises the first letter of each sentence (after periods, question marks and exclamation marks). It runs entirely in your browser, keeping your text private.
FAQ

It capitalises the first letter and any letter following a period, question mark or exclamation mark.
Does it fix ALL CAPS text?
Yes — it lowercases everything first, then capitalises sentence starts.
Will proper nouns be lowercased?
Yes, it cannot know proper nouns, so review names after converting.
