Is there an AI program that can help me?

I have a series of paperback books that are falling apart on my shelf, so I bought digital copies of the books. But then I had an idea that maybe I could try my hand at book binding and figured that these books that I already own would be a good place to start/practice. So I found a way to copy and paste from the digital copies I own to Google Docs, but wow, the formatting is horrendous. I tried doing it manually, but 4 hours of reformatting and I’ve only finished 20ish resized pages. So, is there an AI program I can use that will help me reformat 12 books of ~200 pages each?

For examples of the formatting and fixing I’ve been doing, there is extra punctuation and spaces in some places and missing punctuation and spaces in other places. Also, there is little to no separation of paragraphs and because I’m trying to resize this from a small paperback to something a bit bigger, the page and chapter breaks are in odd places.

Any help, even just a different subreddit or website to check would be helpful.
