Default Unique data in column or row in Excel

Hi Ali,

Try to use this formula in Data/Validation/Custom:

=ISERROR(MATCH(A1,INDIRECT("A1:A"&CELL("row",A1)-1),0))

Regards,
Stefi

I have a problem with posibility of repeating data in column. Of course this
is normal behaviour of Excel, but I need to assure unique data in column. Is
there a way to do this without an extra effort?
