It is a function that allows you to count the amount of blank cells in a range. So if you want to count how many cells were in the range from A2 to A20, the function would be as follows:
=COUNTBLANK(A2:A20)
Countblank function is a derivative of count function and it is doing a very simple task - countblank function counts the number of cells in the range with no data. Actually, if you'll add the results for count/a function and countblank function you'll get the total number of cells in the range (empty and not).
Count cells with numbers: COUNT Count cells with data: COUNTA Count blank cells: COUNTBLANK As an example: =COUNT(A1:A5) =COUNTA(A1:A5) =COUNTBLANK(A1:A5)
