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.

I was given this new task this year. Normally this process is done by hand, by one of the managers, but since it now belongs to me, I look at it as being a little to tedious to do. So I would rather have excel do it for me.

We have about 5 CSRs who handle clients based on the first letter in the clients name. I guess to make this easier to update in the future if the macro would respond to a cell reference for the number of CSRs that would be great. I will need to perform this task Annually, and of course each time a CSR leaves or we hire another one. This way work loads are kept close to the same.

I have a list of letters in column A. Each of these letters has a corresponding number of clients in column B. I have been given the task to try to split these values equally between the 5 individuals. I know that since the numbers don’t all add up and divide equally it can’t be done easily by hand.

I have attached an excel file with what I have in the sheet. Sheet 2 shows what I would like to have as an example as output on the same sheet. (What I put on the sheet is an example of the way I want it to look, are not close to adding up to a "close to equal" total.)

I'm having a problem with a spreadsheet in Excel. I have in column terras, codti problem and several cells that are repeated. I'm stating that terra appear only once, the information in column each issue should appear in different columns with the sum of how often they appear and codti according to terra.

In excel is best illustrated what I mean!

In total, 5267 lines and need to do this with all. You can do this in excel?

Column A = numerical IDs, multiple entries, may have duplicates that should only be counted once in comparison

Column B = numerical IDs, multiple entries, may have duplicates that should only be counted once in comparison

Need: 1 cell that compares all of the A range to all of the B range and returns a a percentage of repeats. So, if there are 50 entries in A, and only 40 are unique, and B includes 10 repeats (unique, not multiple), then the returned value would be 25%.

I have a group of employees who work different divisions and work is not done everyday. I want to count the unique values of a division (only once) per day that the division shows up. Within a week, workers in a division might work 3 days and not other days. I've tried a few array formulas but they count unique within a range and I need the unique value to be based on the selected cell.

Please see attached : Unique Values In Between Dates.xlsx

In the picture below, I need a formula in column E to count the unique occurrences in column A (excluding blanks) if its corresponding value in column B (B1 value) matches that in column D (B2 value). Currently column E is showing the values I would want the formula to return.

At the moment I have a formula as below:

=SUMPRODUCT(--(B:B=$D2),--(A:A<>""))

this will do a countif in column A if column B matches the value in column D, but would not weed out duplicates for me.

Modifying my formula. I have attached the sample workbook below.

I am trying to find a formula that will count the number of unique entries there. I have tried the solutions posted on various websites to no avail (most recently:

If I have multiple entries with different but repeatable text values in one column - how do I count all unique ones ? Is there a function or does it have to be a pivot table of sth ?

I need a Macro (not formula) which compares the comma separated values present in Column "I" with individual values present in Column "D" and generate the count of unique values in Column "J".

I'm running into an issue trying to calculate unique values in a Data column based on a few variables in other columns.

My current formula in Summary tab D4:D19 is {=SUM(IF(FREQUENCY(IF(Data!$I$3:$I$66<$E$1,IF(Data!$A$3:$A$66=$H$1, IF(Data!$C$3:$C$66=A4,ROW(Data!$I$3:$I$66)))),ROW(Data!$I$3:$I$66)),1)) + SUM(IF(FREQUENCY(IF(Data!$I$3:$I$66<$E$1,IF(Data!$A$3:$A$66=$I$1, IF(Data!$C$3:$C$66=A4,ROW(Data!$I$3:$I$66)))),ROW(Data!$I$3:$I$66)),1))}

This is currently counting the number of times a date value (data column I) appears for that name (A4:A19) in the data when meeting all of the conditions. I need it to instead count the number of times a unique date appears for that name with the additional conditions met (which all appear to work fine).

The results in the pink highlighted cells (Summary column D) should be:

Names starting with A - 3 All others - 2

I've left some other columns in the data with X's so that I can easily convert this back to my working spreadsheet.

I want to count the number of unique companies that joined in different months. I have two columns to work with - date [in time stamp/data format] and company name.

DATE COMPANY NAME

10:42 02/01/14 A

11:33 02/01/14 B

16:14 07/01/14

The results should equal -

Jan 14 - 2 Feb 14 - 2 Mar 14 - 1

The closest I have gotten it to remove duplicates =SUMPRODUCT((B1:B15<>"")/COUNTIF(B1:B15,B1:B15&"")) and to count the months =COUNTIF(A1:A15,"*01/14") but I cant seem to link the two.

I'm working with a data set (attached) that tracks financials at both the job and item level (in my customer's data - a unique job can be made up of a single or multiple items).

I've successfully built a formula (in column C of the attached) that counts the total number of items and their associated $ values that were invoiced in a given month based on my customer's requested item-type categorizations (i.e. "Exact Match", "Similar", "Inferred", "Cost-Plus").

The problem I'm running into is building a formula that counts the first unique instance of the Job ID associated with those items. For example - in cell C33 on the attached - The total number of items invoiced in June that were "Exact Match" was 10. These items were spread across 9 unique jobs - and that's where I'm struggling - to build a formula that only counts the first unique instance of the corresponding Job ID in Column C.

The formula I'm having trouble with is located in Cell D12 on the "Dashboard" tab of the attached.

The formula as I have it is returning a result of 8 - because it's summing the "1"'s in Column I on my "Invoice Data" tab - however it should read 9 (Filter Column Q on the "Invoice Data" tab to "June", Filter Column AQ on the "Invoice Data" tab to "Exact Match", and then sum the unique job IDs in Column C).

I'm looking for a formula to generate the number of unique card numbers are in the column...I'm using this daily, simply pasting the new data in so if I want to keep it as automated as possible.

I want to count data that corresponds to 4 criteria for data located in Columns B, C, D and E. However, I only want to count only the unique values in Column A. How do I improve on this formula?

I have an array that I'm using - and it works perfectly: =SUM(If((FREQUENCY(If(LEN(B10:B100)>0,MATCH(B10:B100,B10:B100,0),""),If(LEN(B10:B100)>0,MATCH(B10:B100,B10:B100,0),""))>0),1))

Now, what I would like to do, is see how many of these unique numbers relate to another number in column D See attachment.

I have a large amount of data and I'm trying to count how many unique values I have in one column. I also want to know how many times each duplicate appears. I tried using a pivot table but it's not working for me.

I also tried the following formula: =SUM(IF(FREQUENCY(H:H,H:H)>0,1)) but it's not quite working.

I have several worksheets (Labeled Sheet1,Sheet2,sheet3) What I need to do is to step through each row in sheet3, and do a search in sheet1, it the data was found, then return the row number. I then will need to copy data from sheet1 (rowfound columnA , through rowfound CoulmnBd to sheet3 current working row columnK

I have a spreadsheet that holds customer information. What I want to do is find how many customers there were last month. I have a cell (C1) which has last month displayed as 2009/05. A1 holds the customer ID and B1 holds the date they used us. Each customer may has used us many times and I'm having a nightmare trying to solve this.

Having a large spreadsheet with Columns A to F filled with data.

I'm trying to create a formula that's count the unique value "Order no." (Coloumn F) but only the ones between certain Departments Column(H) a certain "Error type" in Column(J).

I want to count the unique values between 2 dates. He only needs to count the values that match 2 criteria. I want to know how many unique orders were place between 01/10/2012 and 30/09/2013.

In my Data sheet: Colomn X: Customer name Colomn D: Status Colomn AH: Date of order (Day/Month/Year)

I want to count the unique values in Colomn O: Ordernumbers
