Hello,

I have two lists on separate sheets in a workbook. Each sheet contains both
unique records and some records that occur on both sheet 1 and sheet 2 (there
are never duplicates within the same sheet). I want to be able to create a
master list on sheet 3 that includes only the unique records from sheets 1
and 2.

Each sheet contains up to 20,000 records across 25 columns, meaning that I
could be looking at a master list of 35,000 records.

I have found and tried the array formulas listed on www.cpearson.com and
while I can get these formulas to work, Excel keeps crashing when I try to
use the formulas across so many records.

I would appreciate any help with this.
