Lesson import issue

Im trying to import some lessons, specifically, they are Assimil lessons in which I have extracted the lyrics from the MP3 files

I want to maintain the line breaks, as each line represents a spoken sentence. But when I copy and paste or load the .txt file, it removes all newline breaks. Is there a way to resolve this? Or some other character combination that is required to represent a line break? I don’t want to have to manually format each lesson after importing them only to separate the lines, there’s 100 lessons…
