SUMMARY

In Microsoft Excel, you can use the FREQUENCY() function in a SUM(IF()) array formula to count the number of rows in which an item appears within a specified range.

To count how many rows in which a value appears in a specified range, use the following formula

=SUM(IF(FREQUENCY(IF(range=item,ROW(range)), IF(range=item,ROW(range)))>0,1,0))


where "range" is the range that you want to search and "item" is the number or text string you want to find within each row. If you are searching for a text string, include quotation marks around both instances of "item."

NOTE: The formulas discussed in this article must be entered as array formulas by pressing CTRL+SHIFT+ENTER in Microsoft Excel for Windows or by pressing COMMAND+ENTER in Microsoft Excel for the Macintosh.

MORE INFORMATION

For example, to find out how many rows in which "XXX" appears within the following range

   A1: XXX         B1: XXX         C1: XXX
   A2: YYY         B2: XXX         C2: XXX
   A3: DDD         B3: DDD         C3: YYY
   A4: XXX         B4: YYY         C4: DDD
                

use the following array formula:

=SUM(IF(FREQUENCY(IF(A1:C4="XXX",ROW(A1:C4)), IF(A1:C4="XXX",ROW(A1:C4)))>0,1,0))


This formula returns the value 3, indicating that "XXX" is contained in three rows of the range.
