You could put this formula in C1

=ISNUMBER(MATCH(A1,B:B,0))

and the do a DataAutofilter on column C, and select the TRUE value from
the dropdown, then delete the visible rows.

Hi,
I have 2 columns of data i'm working with. column 1 is dec.04 dates,
column
2 are jan,feb,mar.05 dates. i had to identify which names in the dec.04
are
also in the '05 column. i used the VLOOKUP formula and returned the
result
in column 3 and i got the information i needed. Now i want to delete
those
names in the dec.04 column. is there a formula to delete these
names/dates?
so column 3 is showing all the names that i need deleted in column 1. can
you help?
thanks!!
