Paul,
I don't know if this is acceptable but you could give it a try:

Set up a range named "MySheets" with your sheet names.

Assuming data is column A on all sheets, put this formula in "spare" column
on EACH sheet: enter with Ctrl+ShifT+Enter and copy down as required.


=SUM(IF(--COUNTIF(INDIRECT("'"&MySheets&"'!$A1:$A20"),A1)0, 1,0))

Change range(s) to suit.

Any result 1 indicates a duplicate somewhere. You can filter on " 1"

there any way you can check if the same record (email address) is duplicated

I have each page sorted in alphabetical order so you can manually scroll
each page and look for duplicates as they appear together.
Is there a way you can get excell to check if duplicated data exists in
different cells on different pages?
