Let's say we have a workbook with two tabs, my list and monthly list. FOr
example in my list:
NAMES
mike
john
jim
sally
mary
sue
bill
Every month we first clear the data in monthly list and then import the new
month's data starting in cell A2:
Person
david
ivan
jim
john
mary
mike
sally
trevor
wilber
Some names are old, some are new. In cell B2, enter:
=COUNTIF('my list'!A:A,'monthly list'!A2) and copy down. We see:
Person Flag
david 0
ivan 0
jim 1
john 1
mary 1
mike 1
sally 1
trevor 0
wilber 0
The names with zero are new names. Trun on AutoFilter for column B and
select only rows with zeros. Copy the visible names and paste into the my
list tab.
