How can I setup in Excel Worksheet Column a number is not repeat?
Hi Shahzad
Select column A and go to Validation (on the Data menu) select "Custom" in the "Allow" box and enter the formula: =MATCH(A1,$A:$A,0)=ROW(A1) then click OK Any unique number is now allowed in column A but a duplicate will give an error Shahzad Zameer wrote: Dear All, I want that in a Column a number should not repeat again.
