How to find the rows existing in one column but not the other?
 

Hi,
I have a first worksheet containing 22000 rows of names and 50 columns
of various data, and I have a second worksheet containing 16000 rows of
names without any data columns, the names in the second worksheet are
all in the first worksheet. Now I want to pick out those rows of names
with all the data columns in the first worksheet which are NOT contained
in the second worksheet, probably put them in a new worksheet. Please
help.

Best regards,
Fred Zheng

How to find the rows existing in one column but not the other?
 

in the 1st sheet:
Assuming Column A contains Names and Column B is empty (insert an empty
column), put the following in B2 and copy down:
=VLOOKUP(A2,Sheet2!A$2:A$16000,1,False)
This will return the Name from Sheet2 (if found) or #N/A (if not found).
You can use AutoFilter to quickly spot the records that have #N/A in
columnB.

What you do with them now is up to you: Copy, Move or nothing.
