## Count rows with data

The formula in cell B17 counts rows in cell range B3:D17 when at least one cell per row contains data.

Formula in cell B17:

If your data set, for example, has 5 columns change:

- B3:D14 to your cell range
- the array from {1;1;1} to {1;1;1;1;1}, there must be as many 1's as there a columns in your data set.
- also change <3 to <5

Example, your cell range is A3:G14. The formula becomes:

### Explaining formula in cell B17

**Step 1 - Check if cell is empty**

The equal sign allows you to compare each cell in B3:D14 with an empty value "".

B3:D14="" returns an array of boolean values indicating if a cell is empty or not. {FALSE, FALSE, FALSE; ... }

The picture above shows the array to the right and the corresponding values to the left.

**Step 2 - Convert boolean values to numbers**

To convert the boolean array to 1 and 0 (zero) I multiply with 1. The parentheses allow you to determine the order of operation.

I want to compare the values with "" before I mutlitply with 1.

(B3:D14="")*1 returns {0, 0, 0; ...)

The picture above shows the array to the right.

**Step 3 - Add values row-wise**

The MMULT function is great for adding values row by row, however, it can not handle boolean values. The function returns an array of values.

MMULT((B3:D14="")*1,{1;1;1})

There are two arguments in the MMULT function, array1 and array2.

The picture above shows you the result from the MMULT function in the blue rectangle.

**Step 4 - Check if each value in the array is smaller than 3.**

If there are three empty values in a row that row is empty. That is why I check if each row is less than 3 indicating that at least one cell is not empty.

MMULT((B3:D14="")*1,{1;1;1})<3 returns {TRUE; FALSE; TRUE; TRUE; FALSE; TRUE; TRUE; TRUE; FALSE; TRUE; TRUE; TRUE}

The array is shown to the right in the picture above.

**Step 5 - Count rows**

To be able to sum the array of boolean values I have to multiply with 1 to convert them to 1 or 0 (zero). TRUE = 1 and FALSE = 0.

SUMPRODUCT((MMULT((A3:G14="")*1,{1;1;1;1;1;1;1})<7)*1)

becomes

SUMPRODUCT({TRUE; FALSE; TRUE; TRUE; FALSE; TRUE; TRUE; TRUE; FALSE; TRUE; TRUE; TRUE}*1)

becomes

SUMPRODUCT({TRUE; FALSE; TRUE; TRUE; FALSE; TRUE; TRUE; TRUE; FALSE; TRUE; TRUE; TRUE}*1)

becomes

SUMPRODUCT({1; 0; 1; 1; 0; 1; 1; 1; 0; 1; 1; 1}) and returns 9 in cell B17.

Why not use the SUM function? Then you would have to enter the formula as an array formula.
