Excel’s COUNT functions can help you count cells with numbers, text, or blank cells. Excel actually has a small family of COUNT functions, but the most useful are:
COUNT: Counts cells that contain numbers; blank cells and cells with text aren’t counted. Syntax: = COUNT(A2:A10).
COUNTA: Counts cells that contain any kind of data, including numbers and text. Syntax: = COUNTA(A2:A10).
COUNTBLANK: Counts blank or empty cells. Syntax: = COUNTBLANK(A2:A10).
