Counting the Number of Blank Cells

One of the worksheet functions provided by Excel allows you to quickly and easily count the number of blank cells in a range. The format of the function is as follows:

= COUNTBLANK(range)

The function returns an integer value representing the number of blank cells in the range. You should be careful, however. If you have the display of zero values suppressed for the worksheet, a cell can appear blank when it is not really blank. COUNTBLANK returns blank cells, not counting those that would have a zero displayed if you chose to display such values. (How you suppress the display of zero values in a worksheet is discussed in other ExcelTips.)
