In which case just change the 128 to 1:
=COUNTIF($A$1:$DX$1,A1)<1

Thanks David, but what I need is to select row 1 for instance accross all
128
columns and to find if any of the cells contain the same data.

It doesn't sound like a charrting question, but in your worksheet (having
selected your 128*128 range & with cell A1 active), use Format/
Conditional
Formatting/ Formula Is:
=COUNTIF($A$1:$DX$128,A1)<1
and select a format to mark your duplicates.
