I have seen a lot of examples related to unique list ... mais not found what I need.
my problem is the following :
I have 2 lists of items in col A and B
not necessarely sorted
ex :

list1  list2
A       D
E       A
D       G
Z       Z
F       I

I need to make a list of items that have dispareared when I compare List2 to list1 and, a list of items thta have appeared in List2 compared to list1
The result expected are :
1. disapearing (in sorted order if possible)
2. appearing (in sorted order if possible)



Values created in column D have no duplicates. They are sorted from A to Z.

Array Formula in D2:

=INDEX($A$2:$A$6, MATCH(SMALL(IF((COUNTIF($D$1:D1, $A$2:$A$6)+COUNTIF($B$2:$B$7, $A$2:$A$6))=0, COUNTIF($A$2:$A$6, "<"&$A$2:$A$6)), 1), COUNTIF($A$2:$A$6, "<"&$A$2:$A$6), 0)) + CTRL + SHIFT + ENTER.

Copy cell D2 and paste it down as far as needed.

Array Formula in D9:

=INDEX($B$2:$B$7, MATCH(SMALL(IF((COUNTIF($D$8:D8, $B$2:$B$7)+COUNTIF($A$2:$A$6, $B$2:$B$7))=0, COUNTIF($B$2:$B$7, "<"&$B$2:$B$7)), 1), COUNTIF($B$2:$B$7, "<"&$B$2:$B$7), 0)) + CTRL + SHIFT + ENTER.

Copy cell D9 and paste it down as far as needed.
