Count Unique Duplicates In Two Columns
Jan 25, 2010
I need a one formula solution to compare two columns for duplicates and count the number of matched pairs. Need to ingore blanks. Can have matched numbers or letters. Asterik denotes a blank (empty) cell. Also only consider the first matched pair if there are more than one matched pairs.
Col A Col B
a
b a
* b
c c
d y
x f
f z
f z
In this case I only want to consider a:a, b:b, c:c and f:f, resulting in the count of 4.

I have a spreadsheet will a large amount of invoice numbers, some of which are multiple occurrences of the same number. I need to count the duplicates as one unique record and sum but I need to sum the total $ amount of each amount attached to each occurrence.
Please look at the sample to see what I mean.
W234678 has three amounts that are added to give a total amount for that number and it is added to the count as one record.
I had this code kindly borrowed from someone else which helped me find the duplicates but it is not meeting my needs.
Dim rCell As Range, rRng As Range, vKey, lrow As Long
Set rRng = Range("F2:F199")
With CreateObject("Scripting.dictionary")
.comparemode = vbTextCompare

How I can create a simple formula to count unique values/text within a range of cells that contain duplicates, blanks and errors?
For e.g., in Column A (row 1 - 10):
Proj-001
Proj-001
Proj-002
Proj-004
#N/A
#N/A
Proj-007
Proj-002

I have columns from A to AA and need to count the duplicates in at least 2 columns and accordingly need to give them values on the basis of their ratings (A, B, C, D) and type of work (book, article etc) given in yet other columns.
I tried COUNTIF, but that does not work for multiple perimeters
I tried SUMPRODUCT, =SUMPRODUCT(($G$4:$G$3000=$G28)*($AA$4:$AA$3000=AA28)), but that only gives a multiplication of my input without the possibility of giving new values to the output.
I tried AND(IF( but that did not want to work either really...
I think the solution is ifsum, but I do not know how to use it in this scenario...
I know this all sounds a bit blurry, so let me attempt to make it more concrete.
Author Title Year Rating Type Desired outcome
P Marx I 2005 I A I Book I duplicate
A Hegel I 1923 I B I Article I -
B Kant I 1674 I D I Book I -
A Derrida I 2005 I D I Monograph............................

I have data in two columns where column A is a name and column B might be a synonym or might just equal the value in column A. I want to count duplicates if cell A2 matches any other cell in column A or B, unless the only match is with cell B2. If cell A2=B2, but also matches cell A7 then it should be counted as a duplicate. I've searched through a lot of the threads and found a lot of useful information, but nothing that seems to do what I need.

I have two columns in a spreadsheet, and I need to write a formula to determine how many times each combination shows up. Example:
SKU-A Location1
SKU-A Location1
SKU-A Location2
SKU-B Location1
SKU-B Location7
SKU-B Location7
SKU-B Location8
SKU-B Location8
SKU-B Location8
SKU-B Location8
I want it to have the data converted to be like this (with the third column being the the number of times that combination appears):
SKU-A Location1 2
SKU-A Location2 1
SKU-B Location1 1
SKU-B Location7 2
SKU-B Location8 4

I have a spreadsheet which is to record quality checks on work carried out by staff. The spreadsheet has a customer reference number in column B and a Staff reference number in column C.
I can carry out a number of checks on a member of staff on one transaction, so for instance, I could carry 3 checks on one customer number, which would result in the staff ref number being enetered 3 times (there is 1 check per row).
I need a formula to count the number of checks I carry out on each member of staff. My problem is that although 3 checks could be completed on someone, if it is on the same customer NO, it only counts as 1 check. In effect, I need a formula to count the number of staff ref numbers which have a unique customer number eneterd in the adjacent column.
All the cust numbers are unique so would I be able to use a wildcard?

In short, I would like a pivot table to only count unique values, but when I click into the pivot I would like to show all instances of that value. For example:
I have a table of data that I am creating a pivot table from. There are fields for Customer ID, Task Name, Age, and Notes. There will be multiple records for a single Customer ID each time it has new notes.
I would like to create a pivot table that has Task Name in the Row Labels, Age in the Column Labels, and count of Customer ID in the Values, so that, for example, I can see how many accounts have been in the Design task for 2 days. However, when I do this it counts each record, but I would like it to count each unique Customer ID. Also, when I click into the pivot, instead of pulling up one line per Customer ID, I would like it to pull up each instance of Customer IDs in that Task Name/Age combination (similar to doing a DISTINCT in SQL).

I have a list of isometric drawing numbers ending with a [underscore]weld number e.g. 1692-SG-0040-04_05.
Some welds are repaired--in that scenario the amended weld number will be 1692-SG-0040-04_05R1, and even 1692-SG-0040-04_05R2 if repaired for a second time.
On occasion a weld may be cut out entirely and a new weld done. The weld number for that will be 6317-FG-1690-02_06C1.
And here's a wrinkle I've just verified...a cut weld may also be repaired so the weld number will look like 1698-SG-0077-01_04C1R1.
Is there a formula to count these as one weld:
1692-SG-0040-04_05
1692-SG-0040-04_05R1
1692-SG-0040-04_05R2
This as one weld:
6317-FG-1690-02_06
6317-FG-1690-02_06C1
6317-FG-1690-02_06C2
...and this as one weld:
1698-SG-0077-01_04
1698-SG-0077-01_04C1
1698-SG-0077-01_04C1R1

I am having trouble creating a function to count duplicates of duplicates.
An example of the data table 1 is:
Product 1 2nd
Product 1 2nd
Product 1 New
Product 1 New
Product 1 Flt
Product 2 2nd
Product 2 New
Product 2 New
Product 2 Flt
Product 2 Flt
Product 3 2nd
Product 3 2nd
Product 3 2nd
Product 3 New
Product 3 Flt
I created a new table (table 2) and made a list of all the Products on table 1 and removed the duplicates. I now have 3 columns with titles New, 2nd and Flt as follows:
New 2nd Flt
Product 1 XX XX XX
Product 2 XX XX XX
Product 3 XX XX XX
I am trying to count the duplicates for each product (XX), but I can't seem to work it out. I've tried the MS help function, but unsure of the actual formula I need to be using.
I am using Windows 7 and MS Office 2010.

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.

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 ?

col A col B col C
AA 1 dog
BB 2 cat
AA 1 cat
BB 3 cat
The end result is:
AA 1 dog
AA 1 cat
BB 5 cat
In this example there are two examples of AA, but they each have a different animal, so they need to remain separate. BB is listed twice, but has the same animal, so the total for them is 5. I am looking for a way to express this with with a formula. I tried using Sumifs, and it sort of works, but I end up with BB listed twice, and I don't need that to happen....

I was wondering if there is a formula or a vba code to return each number once from a list.
For example I’ve got a list with app. 500 rows and maybe 80 different numbers in there, so one number could be 50 times in the list, another number maybe just once. Is there a formula, which returns me each number once?
Can’t think of any, or do I have to use a vba code be get the information?

I am relatively new to Excel so there may be a easy way to do this that I just can't see. Here's the background:
My raw data contains 10,000+ entries with many duplicates. Each entry though has a time stamp like so:
Unique Identifier: TimeStamp
S1111111111 10th July 02:00
S1111111111 10th July 02:10
S1111111111 10th July 00:50
What I want to do is to isolate the duplicates in this sheet of 10K+ that have the earliest timestamps and delete duplicates with later time. So in the above example, I would only be left with the 3rd entry as it has the earliest timestamp.

I am confident the answer is no, but is there any formula / combination of formulae that will seek out unique values in a list of duplicates (just like filtering unique records only)?
I have a list of many duplicating sales people and I want to just create a column on another sheet that automatically sorts out the unique values (then I will sum their sales numbers with the SUMIF formula).
(By the way, the reason I just don't use the filter function is because the list always changes so I would need to keep applying it.)

I'm needing to generate a unique random value for a database with 3546 cases. The unique random values cannot be duplicates of each other. I tried the =RANDLOTTO function that I learned of in an old post on this board, but that results in "#NAME?" appearing in the first cell. I tried to install the Add-Ins (both the Analysis ToolPak and the Analysis ToolPak - VBA, but nothing seems to happen. Is there another way to generate these numbers?

I want to end up with a list of unique items (nothing repeated) from a variable length list starting in cell B5. That unique list is then placed in cell D3.
I am using the code below (found on Ozgrid) which almost works. But it seems to be dependent on what’s in column A (which I wish to ignore) for it to work.
How can I modify the code so that the results are based on column B only?
Dim Rng As Range
Dim fRng As Range
Dim lRow As Long
Dim Dest As Range
lRow = Range("B" & Rows.Count).End(xlUp).Row
Set Rng = Range("A5:B" & lRow)
Set Dest = [D3]
With Rng
. AutoFilter Field:=1, Criteria1:="1*"
Set fRng = .Offset(1, 1).Resize(.Rows.Count - 1, 1).SpecialCells(xlCellTypeVisible)
With fRng
.AdvancedFilter Action:=xlFilterCopy, CopyToRange:=Dest, Unique:=True
End With
End With

I'm having a problem deleting duplicates from list in excel. I’ve attached a sample. I’ve tried the following:
1-Advanced Filter, Unique Records Only
2-Remove Duplicates function in Excel 07.
3-Pivot Table
4-Colour Conditional Formatting, sorting by colour
5-B2=IF(A2=A3,”Dup”,”Not-Dup”). The entire column returns “Not-Dup”
6-I’ve tried to resolve using the fix shg & teylyn suggested to Hillto in this thread, but am unable to get the ‘Numeric’ Keypad to appear in the ‘Find’ Function.

In column CT between rows 11:210 is the vertical data that includes duplicates. I am looking to create a formula that can lookup each value between CT11:CT210 and return only the unique values horizontally starting in cell CW9 and onwards.
Example: CT11:CT14 looks like
5x20
6x4
5x20
5x8
and so on and so forth..
I would then like this formula to return the above data (which goes all the way to CT210) in this format starting in cell CW9 - 5x20 then CX9 - 6x4 and finally CY9 - 5x8.

what I'm after is a macro to check the contents of Column 'A' against column 'B' and display any duplicates in Columns 'C' & 'D'.
N.B. The headings of Columns C & D are :-
C = Value Found in Column A
D = Value Found in Column B
Any duplicate entries logged in columns C & D should be listed in C2,C3,C4....C20 and D2,D3,D4......D20 etc (in effect creating two new lists)

In my attachment is what i'm working with. In the first worksheet tab, "NOTBA 10 09", i need it to count what's in the other worksheets, minus the duplicates.
So C4 should be referencing to H3:H21 in the 04-Edmonton worksheet. The number it should be showing is 11, however it's counting 15 because there's 5 entries for CDAU034479. Is there a way for it to basically count what's in that column, minus the duplicates?

I am using a CountIf formula to flag duplicate entries in a column of data, in a Column I have "=COUNTIF(P:P,P1)" It returns a number equal to the number of repeats of the data in call "P1". I then sort by that column to isolate all rows which have duplicates in Column "P". The cell has "1" if there are no repeats, "2" if there is one repeat, "3" if there are two repeats, etc. What I would like is a formula which would put a "1" in the cell the first time it sees data, then something else when it sees repeats. That way when I sort, ALL the repeats will be together and can be deleted. Is that possible?

I have a column with something like 20 thousand rows. I would like a formula that basically checks the column for duplicates and numbers the sets of duplicates. So if there are 5 cells that are all "Server10" I would like for the formula to place a one next to all of those cells. And for the next set of duplicates it finds I would for it to place a 2 next to all of those cells. Essentially my end goal is to sort the sheet so that all of the matching duplicates are all together. There might be some simple filtering method here that I'm overlooking but if there is..... I'm overlooking it lol. And to be clear I don't want to eliminate the duplicates, I just want them grouped together.
I've attached a very simple example of what I would like the formula to do. The cells in the right column would be the result of the formula.
