/lit/ - Literature

I read a book and remember seeing a humorously long word. I've forgotten what the word was so I can't control f on an online copy.
Does anyone know if any type of program or website exists where you can copy paste the entire text of a book (essentially treating it as a text file) and break the entire thing down in various ways, including word lengths?

Something like this for example:
1 letter words: 567 occurrences
2 letter words: 300 occurrences
3 letter words: 2734 occurrences

And so on, being able to scroll through all the words in separate categories. That way I would be able to sort by 17 letter words and upwards to immediately find what I'm looking for.
