macro to remove all words w/o any highlighted letters in a 2013 doc?

hi experts! i have HUGE lists of words saved as ms word 2013 docs. they are in the following (entire_word-comma-space) format:
                                                                                                                                 this, sentence, shows, just, like, a, small, snippet, or, sample, of, the, format, i, chose, for, my, docs
                                                                                                                                      (all j's, k's, l's, u's, i's, o's, & p's are highlighted; that is, many of the words in my 10-pg. long docs contain highlighted letters)
                                                                                                                                    i need to delete ONLY the words containing highlighted letters. does anyone know how to script a macro that can do this task in office 365 for word 2013? thanks very much in advance!
