In the cell that you want the result to appear in, enter the appropriate
formula from the following examples.
How to Count the Occurrences of a Number
Use this formula
=SUM(IF(range=number,1,0))
where
range is the range that you want to search, and
number is the number that you want to count.
NOTE: This formula must be entered as an array formula. To enter an array formula, press CTRL+SHIFT+ENTER.
How to Count the Occurrences of a Text String
Method 1
Use this formula
=SUM(IF(range="text",1,0))
where
range is the range that you want to search, and
text is the text that you want to find (the text must be enclosed in quotation marks).
NOTE: The above formula must be entered as an array formula. To enter an array formula, press CTRL+SHIFT+ENTER.
Method 2
Use the COUNTIF() function to count the occurrences of a text string. For
example, use the formula
where
range is the range of cells that you are evaluating, and
text is the text string that you want to count instances of (note that
text must be enclosed in quotation marks).
NOTE: This formula must be entered as an array formula. To enter an array formula, press CTRL+SHIFT+ENTER.
Wildcard characters can be used within the COUNTIF function.
The asterisk character (*) represents more than one character. For example, to count all the cells in the range a1:a10 that contain an "x," you can use the following formula:
The question mark character (?) can also be used to represent one wildcard
character -- for example, to count all cells in the range whose second
character is the letter, such as "ax" or "bx."
