COUNTA function
This article describes the formula syntax and usage of the COUNTAfunction in Microsoft Office Excel.
Description
The COUNTA function counts the number of cells that are not empty in a range.
Syntax
COUNTA(value1, [value2], ...)
The COUNTA function syntax has the following arguments:

value1 Required. The first argument representing the values that you want to count.

value2, ... Optional. Additional arguments representing the values that you want to count, up to a maximum of 255 arguments.
Remarks

The COUNTA function counts cells containing any type of information, including error values and empty text (""). For example, if the range contains a formula that returns an empty string, the COUNTA function counts that value. The COUNTA function does not count empty cells.

If you do not need to count logical values, text, or error values (in other words, if you want to count only cells that contain numbers), use the COUNT function.

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