Adding text from a word doc to a drop down menu

I have created a drop down menu in a form. I want to take a list of criminal offenses from a word document and turn them into choices in this drop down box. The list is extremely long, is there a way I can do this all at once rather than doing each offense one at a time? I tried to copy the text from the word document and paste it into the section for the drop down box but that did not work.
