# Countif Question

Posted by James on June 26, 2001 3:30 PM

I have a worksheet that has numbers like this "303,302,508,408" there are several rows with info like this and I want to count each occurence of a number. Like how many times does 303 show up. I do not want to put each number in a colum by itself. Is there anyway to do this?

Thanks.

James, are you asking how the syntax for countif works?

At the end of your data block (row or column):
=countif(range,criteria) where range is your block of data and criteria is the number you are looking for.
So that you don't have to edit the formula, you can point "criteria" to a cell that allows you to enter whatever number you are looking for.

No. I know how it works. But it does not work with more then one number per cell. I have the numbers seperated with "," and want to count them without putting them in seperate colums. I can write a macro but want to know if there is a easer way?

In the cell there is a set of numbers like this:
302,104,451,096
I want to count over severl cells how many of each number there is. But I do not want to put them in there own colums?

Thanks

James,

OK. I'll assume that a "partial number" doesn't have a repeat in the same cell like in "303,304,303". What I'm going to propose will count such cases once. For the preceeding example, you'll have a count of 1 for 303 and a count of 1 for 304. If this is acceptable to you, read farther.

I'll assume all your entries to be in A from A2 on.

Put all the numbers you'd want to count in B from B2 on.

In C2 array-enter: =SUM(ISNUMBER(SEARCH(B\$1&",",\$A\$2:\$A\$100))+0)+SUM(ISNUMBER(SEARCH(","&B\$1,\$A\$2:\$A\$100))) [ copy down this as far as needed ]

Note1. Hit CONTROL+SHIFT+ENTER at the same time (not just ENTER) to enter this array formula.

Note2. The formatting of the entries should not matter as long as theere a commas to separate the "partial numbers".

Typo & ...

The copy of the array formula I pasted is not the intended one. Here is the correct version:

=SUM(ISNUMBER(SEARCH(B1&",",\$A\$2:\$A\$100))+0)+SUM(ISNUMBER(SEARCH(","&B1,\$A\$2:\$A\$100))+0)

Sorry about that. BTW, this will count repeats also that occur in the same entry/cell.

Re: Typo & ...

It looks good but there can be several repeats in one cell. This seems to only count two. Is there anything else.

Thanks for the Help

Repeats...

James,

The following array-formula assumes cells with 3 numbers (separated by commas). If you have more numbers (hope not too many), it can be extended to cover them too.

=SUM((ISNUMBER(SEARCH(B1,LEFT(\$A\$2:\$A\$4,LEN(B1))))+0))+SUM((ISNUMBER(SEARCH(B1,MID(\$A\$2:\$A\$4,LEN(B1)+2,LEN(B1))))+0))+SUM((ISNUMBER(SEARCH(B1,RIGHT(\$A\$2:\$A\$4,LEN(B1))))+0))

I still expect a column (e.g., B) with distinct numbers for which you want a count. The formula can be array-entered in C1 and copied down.
