Find Duplicate Data - Identify Which Entries Are In BOTH Columns
Apr 27, 2014
I have data (e.g. PPL0106AU) in columns A (Rows 2 to 104) & C (Rows 2 to 303) and need to identify which entries are in BOTH columns.
I've entered in column B: =IF(MATCH(A2,C$2:C$303),A2,"No")
This formula is resulting in a duplicate of column A in column B.

I have attached a before and after image of what I am looking to accomplish.
In the before image, you can see that there are 3 rows of data
- a header
- a repeating model number (in column F) with accompanying data (values in columns G - J are the items of interest)
In the after image, you can see that I took the 3 rows of data and turned it into simply two rows of data
- a header
- the repeating model number
What I did however in the after image, as can be seen, is I took the data that appeared on the repeating row (Row 3 from the Before image), and included the PRICE, COST, BEGIN, and END values in new columns on row 2.
The model number is the same of course, which is why I did it that way.
If the model numbers were different, I would have simply left it alone, as-is.
Is there a way to accomplish this via some functions or maybe even a VBA script?
By the way, if we have to dump all of this onto a new sheet, then so be it.

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

how i can set 'Data Validation' to stop me from entering duplicate values across multiple columns, i can set it for a single column i.e. A1 to A100 but i am after this but for something like A1 to H100.....?
I am currently using this formula in Data Validation:
=COUNTIF($A$1:$A$100,A1)=1
I need something to do this but for multiple columns.

I am looking for either vba or excel method to prevent duplicate entries across multiple columns. The data validation only works when it is input manually by the user and not when it is generated by the formula
What i am trying to do ( assuming " | " are column dividers and each new line is a row)
abc | 2 | bac | 3 | cab | 4
bac | 3 | abc | 2 | cab | 4
abc | 2 | bac | 3 | cab | 4

Can I use a macro in workbook (test 1) to look at a differant work book (Test 2) and look at a range of A2:A20 and look for a duplicate date? If it sees a duplicate date I get a message (Date Taken) I would need to compare about 4 or 5 columns to each other, column A to column A, column B to column B etc. Will this work if the other workbook is not open?

I have a userform that I use for data entry with lots of combo boxes, list boxes and text boxes
One thing i haven't cracked yet is to check for duplicates against two matching fields
If a user (for example) enters 'SAB' (which will be stored in column A) and then 'UK' (which will be stored in column B) and there is already an exact match for both, then I need to inform the user that a matching record already exists
The following is OK: (the dots below are meant to illustrate spaces between the columns!!)
Col(A).....Col(B)
SAB........UK
SAB........USA
SAB........Italy
BUT, if a user then tries to enter:
Col(A).....Col(B)
SAB........UK
I need my userform to register a duplicate entry.
My sub routine is detailed below : .....

I have a approx. 70 excel sheets with thousands of entries. Within a single sheet there are some duplicate entries (based on an account number). I find the duplicate entries by using the excel 2007 conditional formating and then sort by color to only show the duplicate entries. There are often hundreds of accounts that are duplicates. Sometimes there are more than 2 identical account duplicates (could be 3,4 or more). In each entry there is a number representing the rating of said account. These numbers differ within the duplicates. Example............
I am trying to find a formula that will choose a "winner" and enter a "W" based on the highest rating within the duplicate entries and then ideally assign an "L" to the loser duplicate account(s). Sometimes there is no rating, other times the rating could be the same in which case any account (does not matter) can be assigned a "W" and the others an "L"

I now need to look through 4524 rows (columns A,B,C) and identify any duplicates based on column A. After all duplicate data has been identified, I would like to delete out all non duplicates. I searched previous posts, but couldn't find anything that worked for me.

I have a spreadsheet that needs to have a validation drop down list in three cells in every row (D, E, F). There are three items in the list, say, "One", "Two" and "Three".
My only problem is that there can only be one entry of "One" in each row.

I am using old macro code in excel written several years ago. I am trying to educate myself to update and improve the macros I am using but not making much progress. This macro is used to record data from a DDE link to a Data Acquisition System. The D-AQ system sends the data points to r5c3:r5c9 typically. The macro then records the data points in those cells to the next row in sequence on a specific time interval. However, the macro is recording duplicate entries for each set of data points. Sometimes just two, but has been as many as four duplicates. I have a remove duplicates macro to run, after the fact, but preventing them from occurring in the first place is the goal. I included the application.wait method at 10 second intervals after the application .OnTime method, but it isn't preventing the duplicates.
Dim delta_time As Date
Dim Count As Integer
Dim n_rows As Integer
Dim start_row As Integer
Dim col_mov As Integer
Sub initialize_button_set()
start_row = 7
Count = 0
n_rows = Worksheets("sheet1").Cells(1, 2).Value
delta_time = Worksheets("sheet1").Cells(2, 2).Value
Application.OnTime Now + delta_time, "get_data"
Rem Worksheets("sheet1").Buttons.Add 275, 0, 72, 36
Worksheets("sheet1").Buttons.Caption = "STOP"
Worksheets("sheet1").Buttons.OnAction = "Halt"
End Sub...........................

In the included workbook I've got a sheet that needs to be updated every time a userform is completed. So I intend to run a macro after the data is entered to find duplicates, and delete the older row.
so, column A must match then column C must match then look in columns AK & AL to find the newest entry to keep. I also need to delete any rows where column A is empty(light Green), no matter what other columns have data.
In my example sheet all the yellow's match for column A but the bright yellow's are the only "keepers", because one has a different number in "C" and the other is the newest.
Also remember that this is just part of a much bigger, multi-sheet book so I will need to I.D. this sheet in the code.

i currently have two columns (e.g. A2:A400, B2:B20) and i am trying to match all the values in B to A, displaying TRUE or FALSE (if the values from B don't appear in A) in column C.
i have tried using the various formula for duplicates, substituting what i thought would be the correct formula, but to no avail.

I need a way that allows a user to identify, when he has written a duplicate.
For example:
In column A, user typed a string XXX123 that already exists (in the same column),
It will receive a warning, the cell changes color
something that allows indentifying the duplication

I have a spread sheet in which an account number is located in, lets say, column A. There can be multiple duplicate account numbers here, and thats ok.
However, there is another column, Col. B, which has the name of an action. There are multiple "actions" listed, but the each action can only occur once for each account number. I need to identify if an account number is duplicated and if so, does it have any duplicate values in B. If it does, highlight the duplicates.

i have a series of colums in which i have a formula for checking if each proceding row has the same value in the cells above ie duplication. i am using the following formula
= if(and (C4=C3),(D4=D3),(E4=E3)),"yes","") although this seems to work ok, some of the cells in colums D & E are empty.
what should i do to check for this.
what i am attempting to do is check for duplicate rows where the row is only a duplicate if the previous row is identical.

I have two sheets with many rows and about 8 columns. The second sheet is some of the rows copied and pasted from the first sheet. I have been asked to mark on the first sheet those rows that have been copied to the second sheet.
I need to check that the entire row matches before somehow making the corresponding row in the "original" sheet stand out.
Unfortunately, there is no unique identifier that I can search by. I have tried concatenating all columns into a new column on each sheet and then using MATCH but I get #VALUE! error.

I have a large spreadsheet of species activity data and want to separate information from two columns to create a bar chart of when a certain species is active over a 24-hour period. There are duplicates of each species in one column and a unique corresponding time of activity for that species in another, something like the following:
Species A 23:01
Species B 07:09
Species C 13:45
Species D 08:30
Species A 01:55
Species A 22:07
Species C 15:29
What formula can I enter that only selects Species A and their corresponding times that I can copy into a new spreadsheet?

I need to identify repeated code with different text value. The codes in B column appears repeatedly in the list. However some codes have different text value (one time appears with public and another time appears with priv). I would like to identify those codes as 1 if they appear with different text value within the list. I highlighted one code 131775 for reference.

My boss gave me a project and need to be done as soon as possible. Basically, i just need to join all of database and then identify duplicates and put them in another sheet in order to investigate if there are any double payments.
Duplicates can be:
- invoices with same vendor name having same or comparable amounts
- invoices with Invoice No. which match or closely match (in case we're mis-keying)
I've tried so many ways to find duplicates that fulfill the 2 conditions above, but still cannot make it done.

I have a report with ~44,000 line items. From this report, I need assistance generating a report that lists all unique line items. I am having problems trying to identify which line items are duplicates as I need to compare 4 different cells in each line to other lines to determine if it is a duplicate item (compare data from columns A, B, E, F)
For example, raw data may be as follows:
Column A
Column B
.Column E

Note from above, there are two occurrences of a duplicate item. As a result, the output table would only list this item once.
I have attached a sample of the spreadsheet with dummy data on one tab and the desired output on another tab. Note that all the data is broken up into blocks of data that is separated by data that is only in the first column of the row.

Columns A & B contain several thousand Project Numbers (e.g., P1052, PA844, etc.). Many of the Project Numbers in column B are the same as in column A, but column B also has additional (i.e., newer) Project Numbers scattered throughout. Ideally, I would like to use a built-in function (versus a custom function if possible) that compares all the Project Numbers in both columns and then separately lists those that are unique to column B.

I have attached my sample XL sheet. Column A & B will be imported from computer system, only one p/n and quanity. Column C & D will be scanned in from multiple trucks and warehouse, p/n might show up multiple times with different quanities. I need to compare A&B to C&D and come up with a recount sheet that shows the difference as in E&F. Ideally this could be put on another sheet that could be printed out for recounting. Is it possible to do all these different functions automatically. There will be somewhere between 3000-5000 different p/n's.

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".

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.

compare and find exact matches b/w the data in columns J and K in the attached csv file. I would simply like all rows with exact matches to be hidden. I can simply change any code to reflect something like
Selection.EntireRow.delete
later if necessary.
