Hi,

In A1 I have blank containing formulas. In B1 I have in IF function a logical test checking if A1= blank then TRUE. I tried =IF(isblank(a1).... and IF(a1="")... but somehow it returns false. What to do?

To shade all formula cells: Home, Find & Select, Formulas to select all formulas. Then apply a light fill color.

=ISBLANK(A1)=LEN(A1)=ISFORMULA(A1)=ISTEXT(A1)=FORMULATEXT(A1)
