Find Last Duplicate In List Of Data?

Feb 7, 2012

I have a list of data that currently has a conditional format on it of =COUNTIF($F$2:$F2,$F1)>1 so that it will highlight the duplicate but keep the first entry blank. I wondered whether there is a way to identify the last duplicate in the list. i imagine this could be done in a column say with an "L".

Find Large Value If List Is Having Duplicate Data?

Dec 30, 2011

I am facing problem in finding the second large value while my list is having duplicate data.

For Example

my numbers are:-
12,65,45,12,87,90,65,87

if I want to find out the top four value by using the formula:-

=large(A1:A8,{1;2;3;4})

the result is coming like: - 90,87,87,65

instead of this I want the result as: - 90,87,65,45.

Find Duplicate Values From A List

Apr 8, 2014

I need to generate a form letter from values on another sheet. I'm using vlookup and as you know, for duplicate values, only the first reference is given. I have several duplicates and need to pull the correct row data for each instance. I would need to replace each vlookup with the proper formula in my letter.

Find Duplicate Keywords, And List Maximum

Feb 13, 2010

I have rows of 10 keywords. I want the macros to compare the first row against all the rows except itself, then compare the second row against all the rows except itself, the third row against all the rows except itself, basically looking for duplicates...It will then record in a column for each respective row, the max # of duplicates found with another row..

For instance lets say I was looking at the 15th row, and it looked for duplicates elsewhere. It only found duplicates in the 4th row and the 5th row. In the fourth row, there were 5 keywords common, and in the 5th row there were 7 keywords common. Therefore the max # of common words is 7 for the 15th row, and that is what is recorded.

In addition the number of rows will probably vary it could range from 1 to 500. I included an excel spreadsheet that has visually speaking how this could work, maybe using COUNTIF. Basically it counts the # of common keywords for one row with all the other rows, pastes the count #s to the right, then finds the max of those count #s, copies the max into another column, then clears the count #s, and looks up the next row, repeats the same process. It is easier probably if you look at the attached spreadsheet to get an idea of what i am talking about..

How To Find Duplicate Data And Delete Row

Mar 29, 2012

I found a lot of information on this but not what I need. I have 8 columns A - H. Column D has some duplicate numbers. I would like to find the duplicate numbers in column D (they are all one right after the other) and delete the entire row leaving only the first. I do not need to sum or anything, just delete the row with a duplicate number. If there are 2 or 3, I just end up with one.

Data Validation - How To Create Dropdown List That Excludes Duplicate Data

Sep 26, 2013

I'd like to create a drop down list in data validation from a column of data that contains numerous duplicates.

For example, let's say column A contained hundreds of transactions with either North, South, East and West, how could I create a drop down list in another cell that only had four selection options?

Name Range Of Worksheets And Find Duplicate Data In Column In Each Sheet

Jun 11, 2013

I have made up 7 worksheets that are completely identical with exception of course to the data they contain. I have a master sheet that contains some of the data from each of the other sheets that will be shared between them. Things were working very well until I discovered that some data was duplicated on a couple of the sheets; and I am in need of adding more worksheets.

The formula I am using for this will not allow me to have more than the 7 worksheets. It is an IF statement array. So now I am wondering how will I be able to add these extra sheets. I would like to use my worksheet names in a range but have evidently done something wrong and could not get that to work before, ending up with this very long 'IF'. !Can worksheet names be used to create a named range?

Also, I would like to know if there is a way to prevent duplicate data on these sheets. I am using conditional formatting on each sheet now, but that of course only works on the current sheet.

Multiple Data Validations (List And Preventing Duplicate Selection)

Jun 30, 2014

I have created a Data Validation list in one of my spreadsheets which works fine. The list itself has no duplicates which is fine but when I select my entries in the other spreadsheet, I want to make sure they cannot select the same value twice.

I tried selecting "List" in data validation and using an AND with COUNTIF but it doesn't work.

=AND(Employees, countif($A$1:$A$20,A1)=1)

Find Data Existing In 2 Columns & List Them

Sep 26, 2007

I have two columns of account numbers. Column A would be considered the master list. Column B is data that changes on a monthly basis. What I would like is for a macro to compare column B to Column A and if it finds any account numbers not listed in column A it will insert a row into column A and copy/paste the account number from column B to A. Both rows are sorted assending so if its possilbe I would like the macro to insert the account number where it belongs or maybe just resort column A once it has finished. My knowledge of macros/VBA is very limited at this point

List Duplicate List Values

Aug 24, 2008

I have an excel spreadsheet that is several thousand entries long. There are cases in which duplicate entries will spring up on that list.

What I want to do is come up with a formula that will find the first duplicate entry in that list and then display that entry in cell on another worksheet. If it was at all possible, I would also like to have the row that the duplicate entry is contained on display as well, in a different cell of course.

I do not want to highlight them using conditional formatting since I have used that to perform other tasks on that sheet and that wouldn't display the entries in a different cell for me, and I would prefer not to use a macro to perform this function it that was at all avoidable.

Find Duplicate Entries

Feb 14, 2007

Got a workbook with 4 worksheets and sometimes we need to cut and paste a row from one worksheet to another, now thats easy now as we are all human and sometimes it gets copied and we have duplicate logs.

Now each sheet has usually not got that many rows in it, but that spreadsheet is getting sent to the highest people in the company and any mistakes look poor.

What i'm looking for is a way that i can highligh any rows that a duplicated in each worksheet. I can do it in each worksheet using conditional formatting with something like = COUNTIF($A8:$A$20,A8)>1. but don't know how to check that is not on any other worksheet. On every worksheet only need to check Col A for the duplicate information

Find Duplicate Characters In A Cell?

Feb 5, 2011

The background to my problem is that I'm trying to create a unique dictionary for a game I'm programming. I have imported the dictionary into Excel and need to manipulate it with the following conditions:

Word length can only be 3-5 characters longWord cannot contain special characters like hyphen or apostropheWord cannot have repeated characters

I got the first two criteria done using pretty brute for methods. The first using the LEN function to find words greater than 2 and those less than 6 and then comparing those two lists to get the list of 3-5 character words. The second I did manual search for characters and replaced them with six random characters so they would fail criteria 1 and be filtered out.

The last one I'm having problems figuring out. The game I'm programming only lets you use a letter once. So words like "dad" (or coincidentally enough "mom") would not be valid.

Is there a way I can look at the words in the cell and see if any character is repeated and then act upon that (e.g., copy to another column if no letters are repeated)?

Find And Isolate Duplicate Criteria

I have a worksheet that tracks errors (10 different error types are tracked) that may occur on anywhere from 20 to 200 different jobs. What I need to be able to do is find all the jobs for any given day where a specific error has occurred two or more times for that day. Often a specific error will occured many times on the same job on the same day. What I need to end up with is only one row for each job that shows the Date/Time (m/d/yyy h:nn), JobNumber (number), ErrorNumber (text field) by either hiding or deleting those rows that do not meet the criteria.

Find Duplicate And Clear Possible Corresponding Matching Value

Feb 14, 2010

how to reference the drang (named range) and the cell propertly as i keep getting an error.

Everything in the below code works except the parts below in blue

details:
I have in column X lots of names and in column Y (dynamic column
anges as the users chooses them as per the code) and I want to loop through all names in 'X' and if there are multiple of the same names then for the corresponding 'Y' row entry of each be checked and if they are equal (same $ value) then for one of them of cells in the Y column to be cleared.

Basically if the same name appears more than once it will most likley have the same $ value and if i do a calculation on the $'s it will be 2,3,10 times the amount it should be, hence the need for this .

As per the below code I am trying to use 2 for Each loops though I keep getting an error when trying to reference the drng range which has the values in them..
