Question: How do I filter values existing in one range but not in an other?

Answer:

Values-existing-in-range-1-but-not-in-range-2

Formula in B13:

=INDEX(One, MIN(IF((COUNTIF(Two, One)=0)+COUNTIF(C12:$C$12, One)=1, ROW(One)-MIN(ROW(One))+1, "")), MATCH(0, COUNTIF(Two, INDEX(One, MIN(IF((COUNTIF(Two, One)=0)+COUNTIF(C12:$C$12, One)=1, ROW(One)-MIN(ROW(One))+1, "")), , 1))+COUNTIF(C12:$C$12, INDEX(One, MIN(IF((COUNTIF(Two, One)=0)+COUNTIF(C12:$C$12, One)=1, ROW(One)-MIN(ROW(One))+1, "")), , 1)), 0)) + CTRL + SHIFT + ENTER

Formula in B21:

=INDEX(Two, MIN(IF((COUNTIF(One, Two)=0)+COUNTIF(B$20:$B20, Two)=1, ROW(Two)-MIN(ROW(Two))+1, "")), MATCH(0, COUNTIF(One, INDEX(Two, MIN(IF((COUNTIF(One, Two)=0)+COUNTIF(B$20:$B20, Two)=1, ROW(Two)-MIN(ROW(Two))+1, "")), , 1))+COUNTIF(B$20:$B20, INDEX(Two, MIN(IF((COUNTIF(One, Two)=0)+COUNTIF(B$20:$B20, Two)=1, ROW(Two)-MIN(ROW(Two))+1, "")), , 1)), 0)) + CTRL + SHIFT + ENTER
