Surely, some guru guys on this forum, versed in Python, could create a script for this purpose ! Unfortunately, I’m not part of them -:(

However, here is a regex search/replacement that you could run, once your text is completed :

• SEARCH ([.?!])\x20*(\w)

• REPLACE \1\x20\U\2

Notes : This regex verifies and changes any text file as expected :

• It rewrites, first, the last character of each sentence

• Then, it normalizes any amount of space chars, even none, to one space only

• And, finally, it rewrites the first letter of the next sentence in uppercase

• If this letter is already written as uppercase, nothing is modified !
