=LEN(A1)=0

Are you sure the cell is empty...........no extra spaces?

If you enter =LEN(A1) in B1 does it return a 0

Hi. I must be doing something wrong ...

I want to have a conditional format when cell A1 is empty.

I set:

Formula is to:

="len(a1)=0"

Even when the cell is empty, the formatting will not occur. Any ideas?

Thanks,
Mike.
