The SUMPRODUCT function multiplies ranges or arrays together and returns the sum of products. This sounds boring, but SUMPRODUCT is an elegant and versatile function, which this example illustrates nicely.
In this example, SUMPRODUCT is configured with two arrays. The first array is the range that holds product pricing:
Note the reference is absolute to prevent changes as the formula is copied to the right. This range evaluates to the following array:
The second array is generated with this expression:
The result of D5:D9="x" is an array of TRUE FALSE values like this:
The double negative (--) converts these TRUE FALSE values to 1s and 0s:
and returns the sum of products, 168 in this case.
Effectively, the second array acts as a filter for the values in the first array. Zeros in array2 cancel out items in array1, and 1s in array2 allow values from array1 to pass through into the final result.
With a single array
SUMPRODUCT is set up to accept multiple arrays, but you can simplify this formula a bit by providing a single array at the start:
If you want to count the total characters in a range of cells, you can do with a formula that uses LEN, along with the SUMPRODUCT function. In the generic form of the formula above, rng represents a range of cells that contain text. In the example,...
The SUMPRODUCT function multiplies ranges or arrays together and returns the sum of products. This sounds boring, but SUMPRODUCT is an incredibly versatile function that can be used to count and sum like COUNTIFS or SUMIFS, but with more...
