if your text is already a string, then you can use split-string to
turn it into a list, by using “\n” as separator.

You can turn a block of text into a string by using buffer-substring-

alternatively, the following i wrote in my early lisp day that does
what you want. I still use it.

(defun grab-lines (n)
"Delete the next n lines and return a list
where each element is a line."
(move-beginning-of-line 1)
(let (t1 t2 cl (lines '()))
  (dotimes (x n)
      (setq t1 (point))
      (move-end-of-line nil)
      (setq t2 (point))
      (setq cl (buffer-substring-no-properties t1 t2))
      (delete-region t1 t2)
      (delete-char 1)
      (push cl lines)
  (setq lines (reverse lines))
;  (prin1 lines (current-buffer))
