COUNT function
This article describes the formula syntax and usage of the COUNTfunction in Microsoft Office Excel.
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.
Syntax
COUNT(value1, [value2],...)
The COUNT function syntax has these arguments:

value1 Required. The first item, cell reference, or range within which you want to count numbers.

value2, ... Optional. Up to 255 additional items, cell references, or ranges within which you want to count numbers.
Note The arguments can contain or refer to a variety of different types of data, but only numbers are counted.
Remarks

Arguments that are numbers, dates, or a text representation of numbers (for example, a number enclosed in quotation marks, such as "1") are counted.

Logical values and text representations of numbers that you type directly into the list of arguments are counted.

Arguments that are error values or text that cannot be translated into numbers are not counted.

If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, text, or error values in the array or reference are not counted.

If you want to count logical values, text, or error values, use the COUNTA function.

If you want to count only numbers that meet certain criteria, use the COUNTIF function or the COUNTIFS function.
