# Count Unique Occurrences In Column A If Column B Equals Value?

Jul 25, 2014
how to count the unique occurrences in column A based on the value in column B. In the example below, I am trying to count the number of unique names in each state (Illinois=1, Colorado=2, New York=2). I would like the formula to count unique occurrences for the entire column A because I will be adding to the list.

..A.............B............C

John......Illinois

John.....Illinois

John.....Colorado

Alex.....Colorado

Alex.....New York

Steve...New York

Steve...New York

I've got two columns, one with policy numbers, the other with error codes.

A policy could be in the list more than once, so I'm counting the number of unique policy numbers with the function

=SUM(IF(FREQUENCY(A10:F10000,A10:A10000)>0,1))

I want to count the number of errors that are NOT code 00 or code 21. Because the error codes are saved as text, I'm counting the number of errors with

=SUMPRODUCT((B10:B10000"21")*(B10:B10000"00")*(B10:B10000""))

The problem is that since a policy number could be listed twice, when I count the errors, I might be counting the same policy as an error twice. This means that I could feasibly end up with more errors than I have unique policies, which doesn't work.

What I'd like to do is only count the number of errors that have unique policy numbers. That is, I only want to count an error the first time it is in the list, based off it's policy number. Is that possible?

Here's my sample data: [URL]

I'm trying to write a formula that will count the number of unique occurrences in a column, if a specified value is found in a different column.

So I want to count the number of unique values in the "ID" column if let's say the text "NameA" appears in the "Name" column.

ID Name 12345

NameA

NameB

NameA 12346

I am trying to count the distinct times a value shows up in a column, if another column has a 2 in it.

For example:

Columns

A, B

2,P25

2,P25

3,P5

3,P6

2,P5

The results shoud be: (2) Because I only want to count the P25 one time.

I'm using Excel 2010

I would need to count unique frequencies in column A, but only for a specified value in column B.

Example:

A|B

1|1

1|1

1|1

2|1

2|1

2|2

2|2

3|2

3|2

I am using Excel 2007 and found this formula that counts all unique frequencies in column A: =SUM(IF(FREQUENCY(A2:A10,A2:A10)>0,1))

In my example, result = 3 Now, I would need to add the possibility to count only for B=1; in my example, result should be = 2.

I get this work a lot and am looking for a much more effective way of working the dataset,

I have numbers like 1.1, 1.2, 1.3 and so on.......

These come under criteria like (1) = 1.1, 1.2, 1.3 and so on.....

I am look for an automated way of doing a count of any number that falls under this criteria, so I want to count based on criteria (1) it would count all 1.1,1.2,1.3 and so on as one count.

I am attaching a sample document to see how it is laid out. [URL] .....

How do I count unique values in Column A only if the values in Column B match?

A B

1 a

2 a

1 a

4 b

5 b

1 b

The formula would return "2" for "a", and "3" for b. Basically, there are names in column B, and I want to know how many unique things are in column A for each person. If there is a better way than a formula (pivot table?) that would be great - like a table that has each of the names (from Column B) and the number of unique items from Column A next to each unique name.

Been working on this issue for the last couple of days with no luck. I have a column of data that is a data and time stamp, for any date or time like below. This is an ever growing list as users continue to populate the data.

13/04/2014 20:00

28/04/2014 17:30

09/04/2014 13:30

09/04/2014 14:00

03/05/2014 7:30

03/04/2014 11:10

On a separate sheet I have a list of times by 15 minute increments starting at midnight until 11:59PM like below.

12:00:00 AM

12:15:00 AM

12:30:00 AM

12:45:00 AM

I'm trying to count how often a time stamp occurred between two 15 minute increments. ventually I'll be plotting this data on a graph to show where most occurrences happen.

I would like to design a macro that can find a value within a cell in a colunm and copy a value in the row then count occurances of that value next time a match in the colunm is found on a different row, but also do this only if the date range in the row is within a specified range. So a multi-critieria search and copy operation.

To explain a little better here is a simplified example of my spread sheet that is in input for the macro.

A

B

C

D

E

1

PART NO.

date in

date out

comp1

comp2[code]......

Column A lists the coponents found on the same row as the seach critria, in this example "12-3".

Column B lists the number of occurances of the components. This search is limited to a date range input by the user.

So what I can see is the components replaced and the amount of times replaced on a specific item over a fixed time.

*It is difficult to describe this problem without showing the macro output, but this is just an example for the purpose of explanation.

I know a bit of VBA programming and initially I started with an input box that asks for the part number and limit dates.

I realise this is beyond me and wonder if it is possible to list uniqure values in excel and place a count occurrences of each. I have a hugh list of over 400 alpha code i.e ABCD, ABCD, ABCE, BDCE, BDCF ZXYE etc etc. What I'd like to do is pick out all the unique values so I can see what alpha codes are on the list. But then I would also like to count the occurrences of each value/name so I know how many times they appeared on the list.

Col A

ABCD

ABCD

ABCE

BDCE

BDCF

ZXYE

ZXYE

YEZY

CDEF

Col B is where i would like to list all the unquie vaules with a count e.g.

ABCD 2

ABCE 1

BDCE 1

BDCF 1

ZXYE 2

YEZY 1

CDEF 1

I am trying to count the number of unique entries in a sheet, that also satisfy 2 other conditions.

I've attached an example sheet : Example email report.xlsx

The result I need is: The number of unique values in column E, that also have NULL in column G and NULL in column I.

So, in the example, the result would be 7.

I know I can do this by conditional formatting and filtering, but would prefer a formula, and perhaps also a macro that I could apply as the number of rows in each sheet is up to 20000, and each month's sheet will be a different size.

Looking for a formula that will give me a count of unique entries (i.e. duplicate entries to not be counted.)

basically a formula that says look in D4:D4001 and count only one of each entry....do not count the duplicate entries.

I would like to modify the below macro so it only counts a word once even if it appears more than once in a row. The reason I want to do this is so I can get a snapshot of the data without certain terms being over-represented.

For example, in the attached example the word 'Microsoft' appears 5 times in row 4 but I only want this to be counted once. In the whole data set Microsoft appears 20 times but only in 7 of the 20 rows so I would like the count to be 7.

The example is set out as follows: In column B there is a description field which in practice will contain consumer complaints and inquiries. To keep the data anonymous the description is filled out with random words and all other columns are blank. The output of Andy Pope's unique word counting macro appears in I:J.

i'm currently trying to count the number of unique numbers in a Column using this formula:

=SUMPRODUCT((A3:A3002<>"")/COUNTIF(A3:A4002;A3:A3002&""))

So far so good.....But I want to add some conditions like only count the numbers that meet the condition say N1:N3000="SE*"

=SUMPRODUCT((A1:A3000<>"");(AND(OR(N1:N3000="SE*";N1:N3000="INC*")/COUNTIF(A1:A3000;A1:A3000&""))))

On this one I get #VALUE! and i can't figure out why.

I have also tried to put the AND/OR condition before the actual starting of the array of the SUMPRODUCT but nothing.

I have a long list of products in an Excel column. I want to count the number of unique items in the list (the cells contain strings, not values).

I know I can use the "Remove Duplicates" tool in the Data menu, and then use a Count function on the resulting list. I wondered if there was an Excel function or formula that would do it, similar to the Frequency function that does the same thing with a list of values.

As the title says, I need to count the number of unique records (names) in column A, where column L is = to something specific (X,Y,Z,W, whatever) for some statistics im trying to report.

Please see the attached spreadsheet. For role X statistics, I need a count of the unique names from col A, where col L = X. Based on my sample spreadsheet, the number should be 2. For Role Y, it should be 3.

There is the potential for spaces in the rows, and no one will be 'cross role'

I've got a few different methods to just count unique values with specific criteria in the same column, but I just can't make anything work for specific criteria in another column.

I tried to ask this question yesterday -- but it was a follow-up question stuck at the bottom of a thread. So, with your indulgence, here is a simpler version of the question, complete with an attached spreadsheet, if you wish to use it. I also closed the other thread by marking it "Solved", since it answered my initial question.]

The situation:

I have two columns of data. The data is not in alphabetical order, and every column includes duplicate values.

namegender

jones m

martinf

smithf

collinsf

wilsonm

jones m

martinf

hughesm

wilsonm

martinm

smithf

west f

jones m

The challenge:

In one cell, count the number of unique names that appear in the name column 3 or more times... with the additional condition that each unique name (which appears at least 3 times) must include at least one one woman!

The correct result: ...

I want to count the number of unique, or distinct, company names in column [C7], subject to two conditions that will exclude certain unique company names from the count.

I should also point out that most company names appear multiple times in column [C7].

a) Count the unique company names in column [C7]...

b) ...including only those companies who have at least one "Yes" in column [C8] somewhere among their records

c) ...and who also have at least one value equal or greater than "1" in column [C15] somewhere among their records

Note that that there is no requirement that the "Yes" and the "1" ever appear in the same record.

I am able to quite easily count the number of specific values in a cell after the table has been filtered. However, the problem I have run into is that some times the data needs to be placed into the spreadsheet twice (or to be more specific the same subject is associated with several unique data points).

What I need: some way to count the instance of some give value in column D only once based on the presence of a duplicate (unique) identifier in column C. However, when I filter the entire database, it must count *only* the filtered cells and not the hidden cells as well.

Picture:

Column C Column D

111111 M

111111 M

111111 M

[Code]....

Currently calculates: M=9, F=2

Right now it incorrectly states there are 9 "M" from column D when it really should be 5 since 3 are duplicate values. My main difficulty is making sure this continues to work after I filter the entire sheet (say column ZZ) and have a bunch of hidden cells.

Equation currently using to count only filtered values (in this case "males" and "females"):

="M = " & SUMPRODUCT(SUBTOTAL(3,OFFSET(D3:D13,ROW(D3:D13)-MIN(ROW(D3:D13)),,1))*(D3:D13="M"))

For column "B" count all the 1's if column header is equal to name in column A.

For Column "C" needs to be checked if a value was filled in column "I" if yes then check if in column "L" has a value, count all these values.
