Using EndNote 21, I need to change from APA 7th to a Chicago style in my thesis. I have understood that simply changing the format style in the document is not enough as all my citations then disappear. I saw an earlier guide from 2010 to manually change the Chicago script but it didnt work either. Is there no way for my already cited references to be automatically converted to footnotes as citations, or do I really have to change every citation to a footnote manually? Any help soon would be much appreciated.
