Counting nontext cells
Counting nontext cells
The following array formula uses the Excel ISNONTEXT function, which returns TRUE if its
argument refers to any nontext cell (including a blank cell). This formula returns the count
of the number of cells not containing text (including blank cells):
{=SUM(IF(ISNONTEXT(Data),1))}
Counting logical values
The following array formula returns the number of logical values ( TRUE or FALSE ) in a
range named Data:
{=SUM(IF(ISLOGICAL(Data),1))}
Counting error values in a range
Excel has three functions that help you determine whether a cell contains an error value:
ISERROR : Returns TRUE if the cell contains any error value (#N/A , #VALUE! ,
#REF! , #DIV/0! , #NUM! , #NAME? , or #NULL! )
ISERR : Returns TRUE if the cell contains any error value except #N/A
ISNA : Returns TRUE if the cell contains the #N/A error value
You can use these functions in an array formula to count the number of error values in a
range. The following array formula, for example, returns the total number of error values in
a range named Data:
{=SUM(IF(ISERROR(data),1))}
Depending on your needs, you can use the ISERR or ISNA function in place of ISERROR .
If you want to count specifi c types of errors, you can use the COUNTIF function. The
following formula, for example, returns the number of #DIV/0! error values in the range
named Data:
=COUNTIF(Data,"#DIV/0!")
Note that the COUNTIF functions works only with a contiguous range argument. If Data is
a noncontiguous range, the formula returns a #VALUE! error.
Advanced Counting Formulas
Most of the basic examples presented earlier in this chapter use functions or formulas that
perform conditional counting. The advanced counting formulas that I present in this
section represent more complex examples for counting worksheet cells, based on various types
of criteria.
