## SUMPRODUCT if not blank

The above image demonstrates how to ignore blank cells in a SUMPRODUCT formula. The following formula is shown in cell E3.

There is no need for an IF function, simply use the ISBLANK function and then multiply with the corresponding cell range.

The ISBLANK function returns TRUE or FALSE determined by if cell is blank or not. Since we are using a cell range the ISBLANK function returns an array with the same size as the cell range.

The NOT function comes in handy when you want to convert the boolean values to their opposites. For example, TRUE becomes FALSE and FALSE becomes TRUE.

becomes

The next step is to multiply the boolean array with cell range C3:C7.

and returns

The SUMPRODUCT function then adds all numerical values in the array returning 6 in cell E3.

1+2+0+2+1 = 6

### Formula returns blank

Cell range B3:B7 contains a formula that sometimes returns a character and sometimes a blank. The ISBLANK function won't work in this case, see cell B14, it returns 0 which is incorrect.

We need to rely on larger than and smaller than characters <>, see formula in cell B10.

Together like this <> means not equal to. Two double quotes "" is nothing.

B3:B7<>"" is a logical expression and returns an array of boolean values with as many values as the number of cells in the cell range B3:B7.

The parentheses determine the order of calculations, we need it to compare the cell range with nothing before multiplying with the cell range.

and returns

The SUMPRODUCT function sums all values in the array.

and returns 10 in cell B10. 1+2+0+3+4 = 10.
