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.
To learn more about the MMULT function read this:
The MMULT function calculates the matrix product of two arrays, an array as the same number of rows as array1 and […]
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.

Count complete rows
The following formula in cell B17 counts complete rows, in other words, all cells in a row must be non-empty.
See formula in picture above.

Hi Oscar,
Can you advise how to do the same in VBA, with use of dynamic arrays?
This is my attemt, but it returnes an error:
Dim count4deg As Integer Dim tempArr As Variant ReDim tempArr(1 To tNumber) For i = 1 To tNumber tempArr(i) = i Next i With WorksheetFunction count4deg = .SumProduct((.MMult((Stress4deg = "") * 1, tempArr) = 0) * 1) End WithStress4deg is an 2D array with numeric values
tNumber is the number of columns in the Stress4deg array
Regards
Bartek
