Count And Flag Duplicates

Jun 12, 2014

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?

Flag Duplicates Across Columns

Nov 29, 2006

sorting duplicate e-mails across three columns in an Excel spreadsheet.

Precisely, I have three mailing lists (Column A, B, and C) that I would like to sort.

I would like to know what e-mail addresses appear in more than one Column (Mailing List), and I would like to highlight/flag them somehow.

I have attached an example spreadhseet that contains fake e-mail addresses for test purposes. As you can see, some e-mail addresses are duplicated or in triplicate across the 3 Columns. In other cases, an e-mail address may be unique to a specific Column.

In my real spreadsheet, I have approximately 3,500 rows and 3 columns.

Indentify/Flag Duplicates With Formulas

Jun 23, 2006

I have an Excel spreadsheet with 3 columns (A, B, and C) and 600 rows. Each cell in A and B contains a 6-diget number. Column C is empty.

I want to determine whether the number in A1, A2, .A600 appears anywhere in column B. If A(n) does appear in column B then I want to enter a symbol (say a Y) in C(n). If A(n) does not appear in column B then I want to enter a different symbol (say N) in C(n).

What is the formula I enter (and where) that will do that?

Compare Multiple Columns - Flag Duplicates?

Nov 14, 2013

Columns A, B, and C have data (first name, last name, state) - 125k rows. Columns F, G, and H have data (first name, last name, state) - 5k rows. Some of these individuals are bound to appear on both lists, and I need to know which ones are indeed on both lists. So in other words, let's say I've got "John" "Doe" "TX" in cells F1, G1, and H1, respectively. I want to search through columns A, B, and C to find out if there are any instances in those columns of "John" "Doe" "TX" in the same row.

I'm thinking there will be multiple VLOOKUP formulas involved, but I could be way off.

Pivot Table To Not Count Duplicates - But Show Duplicates When Click Into It

Aug 24, 2011

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).

Count Duplicates And Duplicates With Suffix As One Instance

Mar 23, 2014

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

Excel 2010 :: How To Count Duplicates Of Duplicates

Jan 24, 2012

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.

Count Without Duplicates

Oct 13, 2009

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?

Count Duplicates In Column?

Jul 21, 2014

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.

Count The Duplicates In At Least 2 Columns

Jan 20, 2010

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............................

Count Only Duplicates And Not Blanks

May 23, 2012

Is there anyway to make this work without having to enter a specific range. For example I want to count the duplicates in column U, but don't want it to count blank cells.

Here is my formula right now, and it works, but it counts all of the blank cells in the row as duplicates. How can I stop that?

=SUMPRODUCT(--(COUNTIF(U:U,U:U)>1))

Locate Values That Are Duplicates Then Count Them

Mar 11, 2014

I have a spreadsheet that has the following

I have 30 teams with 15 players each

I have teams in rows and players columns with their ID and then name so B2 would be 444 and B3 would be Johnson and B4 would be 429 and B5 would be Smith

What I want to do is run a formula that counts the duplicate ID's not names and then shows them in a list like below

Duplicate ID, Number of times in worksheet
444 , 23
411 , 21
211 , 15

How I can do this.

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.

Sequentially Count Duplicates In List

Oct 2, 2008

I am trying to work out how I can assign a sequential value to sets of duplicate data within a list. i.e. where I have duplicates in a list I want each of the duplicates (that are in the same set) to have a sequential number assigned and for that to start from 1 each time it discovers a new set of duplicates.

RED
GREEN
YELLOW
PURPLE
RED
ORANGE
BLACK
GREEN
RED

Where a colour is duplicated in the list I want it to have a sequential number assigned. When a new set of duplicates is found the numbering starts from 1 and sequentially increases. So the above data list would resulting in the following output

RED 1
GREEN 1
YELLOW
PURPLE
RED 2
ORANGE
BLACK
GREEN 2
RED 3

Have tried variations of the RANK function, but not sure how to get the sequential nu,bering to restart with each unique set of duplicates. I would also like to do this without VBA if possible using the built in functions.

Count Duplicates In 2 Columns, But Not If Column A=b

Jun 20, 2007

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 would do countif, but I do not know my values (this is from a report that I ran from a database) and it would take too long to find all the individual values every time I needed to run this report. So this is what I am looking for (a graph would work too).

A3
A4

ABC
1

ACC

Count Each Item In Filtered Range With Duplicates

Nov 20, 2006

Is it possible that, once filtered, you can count the amount a filled in cells in a column range...BUT! These cells are ID numbers for stocks, so CAN contain duplicates which represent accounts, Therefore, any duplicate will be counted as 1...

eg

12345325
12345325
435ghfdhy
5464OKff
SEDDONF4

[Code]...

As we can see here there are 14 lines of data but only 7 make up the dataset

so if X was the variable assigned to this it would = 7

Is this possible, in a loop or some sort, Would VBA hold all the Instances in its memory???

Count Duplicates In A Cell Then Rank Them And Sort Them

Sep 13, 2006

I would like to have the duplicate numbers in position one ( cell D9:D18), position two (cell E9:E18) and position three (cell F9:18) all counted and then ranked based upon date range in column A.

The number order of precendence is 0-9 with zero being the lowest.

Column (I9:I18) counts the duplicates, draws and no draws of digits 0-9. Column (J9:J18) converts results from column I9:18 into a percent.

I need to add a sort button at the bottom of position 1 (columns H & I 22), position 2 (columns L & M 22) and position 3 (columns P & Q 22)

When the sort button is selected it will sort the data by # of repeats, draws, and no draws as illustrated in (columns I, M & Q) or sort data by Position number from 0-9 as illustrated in (columns H) which will then show data of repeats and percentages out of rank order, because it is in order of number precedence.

Last but not least a graphic bar chart that shows the results ranked highest to lowest from when the sort button is selected with the number at the top of the bar colored black. Bar graph colors to be: top 3 red, middle 4 yellow and bottom 3 blue. This should show a vertical cascade effect.
