How to compare words from .txt file against words in .xlsx file via Python? I will then extract these words by writing it to a new .xls file

Make it a set (outside the loop):

 ??? dictionary = set()

and then add the words to it (inside the loop):

 ??? dictionary.add(cell_range.value)

(Maybe also rename the variable to, say, "words_wanted", because calling 
it "dictionary" when it's not a dictionary (dict) could be confusing...)
