Microsoft Excel 2003 Functions and Formulas - Determine the Number of Blank Cells

If you need to determine how many blank cells exists in a range in a Microsoft Excel 2003 spreadsheet, the =countblank function makes this task easy.

=countblank(RANGE)

RANGE is a range of cells to scan.

For example, assume the following spreadsheet of a person's yearly sales report, broken down by quarter. The spreadsheet will notify the end-user of how many more entries are needed before, presumably, calculations can occur with the data.


    A               B
1   1st Quarter     23
2   2nd Quarter     
3   3rd Quarter	    45
4   4th Quarter     28
5
6                   ="Values Required: " & COUNTBLANK(B1:B4)

The result:

B6 Values Required: 1
