How do I maintain the format (spacing, indents, new lines, etc) of the books that I import?

Whenever I import content it becomes a jumbled mess and it isn’t pleasant to the eyes. I’m wondering if there is anyway for me to maintain the same format? Also is there a way that I can fit the pages on slide in Lingq in the same as in the book? For example, I don’t want a page to be cut up at random places into several slides.
