Counting Unique ID's
Mar 26, 2009
I've got a list that's about 15,000 rows long. Column A has a date and column B has an alpha numeric ID. The list is sorted in order of oldest date at the top, most recent at the bottom. The range of dates is from 1/1/2007 through 3/23/2009. Both the same date and ID show up multiple time throughout the list.
I need to figure out how many unique ID's show up on the list in each given calendar month. I could manually break up the list into months, use an advanced filter and then run a count formula, but it seems like there must be an easier approach.

Ok so I have an excel file, that has 20,000 records/rows of data. There is a column called <STATE>, which could be PA, MD, CA, MT, etc.
I need to know how I can count how many times each state is populated and return the results to a new created sheet called <REPORT>. See example below.
State:
PA
PA
PA
MD
CA
MT
NJ
NJ
Report Results
PA 3
MD 1
CA 1
MT 1
NJ 2
Can this be done?

I have a column (within a database) containing hundreds of Project Numbers
(e.g., P8763, PA3229, P1090.1, etc.), and the same Project Number can appear
more than once in the column. I need to count the number of unique Project
Numbers within that column, based on the criteria of another column. Is
there a way to do that using a combination of the DCOUNTA function and a
formula?

I picked up a great formula from this website to count unique values =SUM(IF(FREQUENCY(K19:K205,K19:K205)>0,1)) and it works great. Thank you to whoever sent it (sorry, forgot who)
I am trying to find a formula to do the same for text.

We've got a column of names. A single name might appear once or two hundred times. The column is over 25,000 lines long, so we don't want to have to count how many different users there are (besides the likelihood of doing it wrong!). Is there some way to make Excel count the number of unique entries in the list, ignoring multiple repetitions of the same name?

I have a data which contains the number of customers who have logged cases with us to find a solution. So the data looks like as shown below;
Case IDCategoryCountrySubject QuestionClosing Details2550EMEADenmarkHi Please help me with the follwing orders, ticket number is JN567786Contact the retail shop12550EMEABelgiumHi please note that the product KA12QT seems to be having hardware problems. the ticket number is JN567786.
Technical issue fixed, DCK JN56778612876APJAustraliaProblem with the music system, resolution required.
The ticket Id logged is JN782238
new CD provided to resolve1
What i need to do is find out the unique ticket ID (eg: JN782238) from all the description provided from column 'Subject Question' and 'Closing Details'. All the ticket numbers start from JN... , however it is very manual for to check every row has a ticket number. I have to do this for many sheets and the data contains atleast 20 to 25000 lines.
Inorder to find this unique ticket number i search through filter by giving the criteria as JN1 and keep doing untill i reach JN9. Once i filter through each of these criteria, i add a number "1" in the last column indicating that this row contains a ticket number.
After completing for all the rows, I add a pivot to check the final count of the the unique numbers, But again i need to remove the duplicates from these count, as there might be several descriptions with the same ticket Id (eg:JN789899). So i add field "Case ID" to the row area in pivot and count of these numbers in the 'Value area' (pivot). Then i look for case IDs with numbers more than 1. I f i find 2 or 3 for a particular case Id then i search this case id in the data and delete one of the count ('1') in the last column.

I have 2 columns with approximately 200K lines of data. There are only 84 and 823 unique values in each column respectively. On my report.
Column A is essentially a customer list, column B is a product list. I am trying to find out how many unique/individual products a customer orders. I have a separate column that has the customers in it (Column G), and in Column H, I want it to count the unique products ordered by customer.
I changed some of the data, but essentially what I attached is what I need.

I need to count the number of unique names (column A) on 3 separate worksheets. Each worksheet represents a facility that people visit. It is possible that the same person will visit all three facilities. If this is the case I want to only count them once, even though they may have numerous entries on each.
I need to get the same result as if I was to copy and paste all of the names from three spreadsheets on to one (which isnt an option) and then count unique names. To do this on one sheet I have been using =sumproduct((A1:A100<>"")/countif(A1:a100,A1:A100))

I have a column of data with 1000 rows. In this column there are duplicated values. I would like to be able to use a function count how many unique values are in the column. Let's say there were 4 duplicates of 250 values in the column. I would like to be able to write a function to calculate the 250. I am very familiar with Excel and am able to acheive the number through subtotals and/or pivot tables. I know I can find how many instances one specific value appears in the column through sumproduct and/or countif statements,

Is there a formula I can use to count the number of unique claim numbers in an excel column?
Is there a way that I can format a cell containing a number containing a decimal point to a number without a decimal point. Example, 205.55 to 20555

I have the following macro (as part of a much bigger set of code that adds some formulas to to cells to return the total number of unique values. The problem is, this part of the macro takes over 10 minutes to run. Is there a quicker way of doing this or am I going to have to just wait it out each time.
The columns B and/or H is a formula. Column W is an string value.
FYI the last row it is counting to is between 4000 and 30000 lines in each of the formulas
Code:
Dim IRMatRow As Integer
Dim IRMisRow As Integer
Dim UKMatRow As Integer
Dim UKMisRow As Integer
IRMatRow = Worksheets("Matching Stats").Cells(Rows.Count, "H").End(xlUp).Row
[Code] .........

How can I count the number of unique values in a column?
I have a spreadsheet that lists transactions that occurred over a one-year period (2007). I need to determine the number of days our facility was operational. No transactions on a particular date (25-Dec-07, for example) and the facility would be considered to have been closed on that date.
On the days that the facility was open, multiple transactions would have occurred on those open days and those multiple tranactions are all reflected in the worksheet.
So I need to count each occurrence of '01-Jan-07', '02-Jan-07', and so on.

=SUMPRODUCT(--(LEFT(Apr08WFA!$A$1:$A$4000,2)="zz"),--(TEXT(Apr08WFA!$F$1:$F$4000,"mmmyyyy")=TEXT(B6,"mmmyyyy")))+SUMPRODUCT(--(LEFT(Apr08WFA!$A$1:$A$4000,2)="zz"),--(TEXT(Apr08WFA!$F$1:$F$4000,"mmmyyyy")=TEXT(B7,"mmmyyyy")))
this counts the number of entries on sheet Apr08WFA when value in range F1 to F4000 is either apr2008 (cellB6) or mar2008 (cellB7).
this works in principle but does not catch all.
I want to amend the formula to catch new entries appearing on a sheet called May08WFA that were not on Apr08WFA but with the same condition of "zz".
So data on May08WFA will be compared against Apr08WFA and new entries counted.

I want to paste a list of customers into a sheet and then have a formula that counts the number of customers. So, even if a customer appears 10 times it would only count it once and and continues down the column and counts the next company name and so on. Then it gives me a total of the number of different companies in that column.

I found the following formula online while searching for how to count unique instances of a number in a list. The list may have blank cells or repeated numbers but this formula works. =SUMPRODUCT((A1:100<>"")/COUNTIF(A1:A100,A1:A100&""))
So my question is...can someone verbally explain just exactly what is going on? i.e. I don't understand the <>"" in the sumproduct argument or the &"" in the second argument of the countif.

I need counting unique values with a number of given conditions. I need this to be a formula so that I can just add data to my spread sheet and it will automatically calculate.
The formula I have is:
SUM(IF(FREQUENCY(IF(A:A=Z1,IF(B:B=Z2,IF(C:C>Z3,IF(D:D<=Z4,G:G)))),G:G),1))
The goal is to count all of the unique value in column G:G that meet certain criteria (have ending times greater than Z3 and beginning times less than Z4, etc.). Once I get the formula to work, I'll simply drag it down to have it calculate for similar lightly changing criteria (like different beginning and ending intervals). However, the formula doesn't seem to be working. It's only giving me zero values (I have "ctrl-shift-entered").

I'm working with a set of text values. The sets of text can be either 2 or 3 chars long (in this example 2), and are separated with a pipe. The end char for each set of chars in fixed. In this case a Z.
I'm looking for a formula which counts the unique / distict number of sets of chars. I have been trying to use COUNTIF with a wildcard (?Z), but unfortunately I haven't been able to find the correct formula yet.
For example.
|AZ|AZ|AZ|BZ|AZ|AZ|BZ|AZ|BZ|AZ| -> 2 (AZ, BZ)
|AZ|AZ|AZ|BZ|CZ|AZ|CZ|AZ|BZ|AZ| -> 3 (AZ, BZ, CZ)
|CZ|BZ|AZ|BZ|CZ|AZ|EZ|AZ|FZ|AZ| -> 5 (AZ, BZ, CZ, EZ, FZ)
|BZ|BZ|AZ|BZ|CZ|AZ|EZ|AZ|GZ|AZ| -> 5 (AZ, BZ, CZ, EZ, GZ)

I am looking to count the unique amount of customers who are listed in column C based on the criteria that they purchased the product on the 1/08/2014 and that the product came from Department 3. The output I am looking for in this example would be 3. I can do it for this example but when I have 300 different customers it starts getting tricky and I'm a bit stumped on how to incorporate an array formula into a countifs() function or whether there is an alternative.
Date DepartmentCustomer
1/08/2014 3 A
1/08/2014 3 B
1/08/2014 2 C
1/08/2014 3 D
4/08/2014 3 A
5/08/2014 2 A
5/08/2014 3 D

Every other line is the planned production and the others are filled in after as the actual production
I have a sumproduct formula right now that looks if the line is considered planned production and then if there is a number greater than 0 planned on that day. The idea is to tell me the number of Stations scheduled to run that day.
Here is my problem- if a station is running two different products it gets counted twice.
I am trying to find a way that once a station is counted it only gets counted once even though they are on seperate lines.
Attached is an example of what I have with the formula and below that is what I am looking for

I want to count unique items in a list with an array formula, like the items is in 3 columns A,B,C are from row 2 to 101. Now i use an array to filter out some rows in the columns of B,C & then count unique items in Column A.
so,
column A has "30 diffrent names repeated from A2 to A101"
column B has numbers 0 to 100
column c has value either 0 or 1
now i use an formula TO filter out rows in column B & c
formula =count(IF((B2:B101>0)*(C2:C101<>1),1))) using ctrl+shift+enter
now what should i suffix or prefix to this formula to count unique values in column A.

I am trying to count the number of unique items in a single column (~5,000 rows of data). For example, I may have the following data
a1 = apples
a2 = pears
a3 = oranges
a4 = apples
a5 = apples
a6 = apples
a7 = pears
in this case number of uniques items is 3
Right now I am using a Pivot Table to figure out the number of unique items but I am sure there is an easier way to do this.

I need to identify the number of occasions on which a product type is bought by a customer in isolation from other product types. I have attached a sample to illustrate. The actual data is more complex and is actually medical data concerning issue of oral or IV drugs. There are many thousands of records.
To clarify, in the example, there was only one occasion when Bread was bought on its own by a particular customer on a particular day. The way the data is presented, 'Bread' could be listed before 'Milk' or, as with 'Steve' on the 2/4, it could be in the middle of a series of 'Milk' purchases. I can sort by date/name/type, but I cant work out a formula to resolve the count.
