Hello,

Say in Workbook 1, I have the following list

a

b

c

d

e

In Workbook 2, I have the following list

a	description of a
c	description of c
d	description of d
e	description of e
g	description of g
h	description of h
i	description of i
j	description of j
k	description of k

How can I in Workbook 1, return the list of range that are not found?

In this case, it should listed out g to l
