# COUNTIF

Hello Everyone

I have a sheet with data.. example

Column 1    Column 2
Apple 1          Pear 1
Apple 2          Pear 2
Apple 1          Pear 1
Apple 3          Pear 6
Apple 1          Pear 7

Another Sheet With:

Column 1      Column 2
Apple 1              2
Apple 2               1
Apple 3              1
Apple 4              1

Is basically looking at column 2 of sheet 1 to determine how many unique entries
belong to Apple 1 etc...

Your example seems faulty. There are 3 'Apple 1' not 2.

As Martin stated above, the count for Apple 1 seems incorrect in your example as there are three listed.  However, assuming that the number 2 is just a typo, I think the following formula will do what you need.

=COUNTIF(Sheet1!A2:B6,A2)

I've attached a spreadsheet with your first set of columns in Sheet1 and the second set of columns (with formulas) on Sheet2.  Note - You can use COUNTIFS in place of COUNTIF and still get the same results.  The upside to COUNTIFS is you can list multiple criteria.

Hope this helps!

Yes, there are indeed 2 distinct Apple 1's (you have to look at column B as well, correct?)

Put this formula in Sheet 2, cell B2

[B2]=SUMPRODUCT((Sheet1!\$A\$2:\$A\$6=\$A2)*IF(COUNTIF(Sheet1!\$B\$2:\$B\$6,Sheet1!\$B\$2:\$B\$6)=0,"",1/COUNTIF(Sheet1!\$B\$2:\$B\$6,Sheet1!\$B\$2:\$B\$6)))

Hit CTRL-SHIFT+Enter to confirm as an array formula.  Then, copy down as needed.  Note the bounds of the formula are to row 6, so you can extend that as needed.

See attached and I get the same results you do, except there is no Apple 4 in the first sheet, lol ;)

Hi

Another option..

=COUNT(IF(FREQUENCY(IF(Sheet1!\$A\$2:\$A\$6=A2,MATCH(Sheet1!\$B\$2:\$B\$6,Sheet1!\$B\$2:\$B\$6,0)),ROW(Sheet1!\$A\$2:\$A\$6)-ROW(Sheet1!\$A\$2)+1),1))

Array formula. Confirmed with CTRL + SHIFT + ENTER

Thank You Dave!  This is exactly what I was looking for.  I also appricate the attachment as an example!
