The Excel function: COUNT
Description
The COUNT function counts the number of cells that contain numbers, and counts numbers within the list of arguments. Use the COUNT function to get the number of entries in a number field that is in a range or array of numbers. For example, you can enter the following formula to count the numbers in the range A1:A20:
=COUNT(A1:A20)
In this example, if five of the cells in the range contain numbers, the result is 5.
