Hi everyone. I have some text that I would like to automatically insert sentence breaks into. At some points in the text there are instances where one sentence endsThen another one begins with no full stops/periods or spaces between.

I'd like to run code that finds lowercase/uppercase pairs and inserts ". " between them while keeping the same letters.

I think it's something like if ([a-z])([A-Z]) then ([a-z]). ([A-Z]) but this doesn't work. Can anyone help, please? Many thanks! :-)
