Is there an easy way of finding out if Column B has the same data of any cell in Column A.

I am under pressure so any help appreciated.

What is the shortcut key for Format Selection?
Ctrl+1 (the number one) will open the Format dialog for whatever is selected.

You could use COUNTIF eg

in C1 use =COUNTIF(A:A,B1) copy down, then filter to show those with 1 or more.
