Delete Duplicates (18k Rows)

Dec 24, 2009

I have a list of 18k rows, and about 7.5k are known duplicates. The delete duplicates button will not delete the duplicates (except it keeps returning 41 duplicates for an unknown reason, but there definitely thousands more it is missing). I tried the remove duplicates button, advance sort, coloring cells, and some macros. The list is the combination of two lists, one older one just compiled, I was able to seamlessly delete dups in another list.

Delete Duplicates (3705 Rows)

Jul 20, 2005

I have a sheet of Data containing 3705 rows. It has plenty of duplicates. Column A is where is located the identification. I need to delete the rows that are duplicated, in order to have only one row for each identification number. I tried to create my own VBA macro to do so, but it seems it doesn't delete all the duplicated rows and it seems to even delete unique rows.

Sub Duplicates()
Dim lstRw As Long
Dim i As Long
Dim j As Long
Dim m As Long
m = 1
Dim Compteur As Long
Compteur = 0
Application. ScreenUpdating = False
Let lstRw = Sheets("UE"). Range("A65536").End(xlUp).Row
For i = 2 To lstRw
'With Worksheets("UE")
SumNumber = Range("A" & i).Value.....................

Count Duplicate Rows Then Delete Duplicates

Mar 15, 2009

I have two columns of data, and I need to create a third column to count the number of times that same line appears in the document (and then remove all but the first copy of that line). my data looks as follows (and it is sorted so all duplicate rows appear directly next to each other):

Adam1998 | Jan
Adam1998 | John
Adam1998 | John
Adam1998 | Paul
Adam1998 | Peter
Adam1998 | Peter
Adam1998 | Peter
Adam1999 |John
Adam1999 | Paul


I need this to look as follows:
Adam1998 | Jan | 1
Adam1998 | John | 2
Adam1998 | Paul | 1
Adam1998 | Peter | 3
Adam1999 |John | 1
Adam1999 | Paul | 1

Delete Entire Rows With Duplicates In Two Columns Only

Apr 20, 2012

I need excel to delete entire rows if there are duplicates in two columns combined.

So, if I have this sample data (in reality I have a lot more columns)

1 Tr. ID Last Name First Name Sex
2 RBM_A Miller Johnny M
3 RBM_A Bayron Josephine F
4 RBM_A Jackson Reynaldo M

[Code] ........

I want excel to delete only row 9, not 11, 13 or 14.

So far, if I look for duplicates in both columns it marks duplicates in either one. Also if I delete the duplicates, it deletes them only in those two columns, leaving me with distorted data (in this example, row 14 would have no last or first name, but only the values "RBM_C" in column B and "F" in column E.

Delete Rows Based On Duplicates In X Columns

May 14, 2006

I've been looking through various forums looking for a macro for a particular task, but I have not found something that works yet. Maybe someone could help me out? It's pretty straightforward situation.

I need a macro that removes an entire row when: information in column B and column C are both found in other rows ( duplicates).

I'm dealing with a worksheet with store record information ... Store Name (column B), Street Name (column C), State/Province, etc. I import new store records all the time and many are invalid because they share the same name and street address and therefore need to be removed. The ones that Iíve played with unfortunately end up deleting the cells only and not the entire row.

It's a tedious process to do manually remove entire rows (for duplicate column B&C) when dealing with thousands of rows and I would very much appreciate any assistance or insight into how simplify the process with a macro. I've attached a sample of what I'm working with.

How To Delete Both Duplicates

Apr 10, 2014

I've attached a test excel to this post. Column C contains several identical email addresses. I need ALL the rows containing the duplicate data removed, not leaving one remaining as Remove Duplicate Values normally does.

I'm going to be doing this with many Excels all with differing amounts of data surrounding column C. I need a reliable way to achieve this, regardless of how many extra data columns exist. If there is a duplicate of data in column C, all rows containing that data need to go, regardless of what other data may also be present in those rows.

Delete Duplicates In Column D Only?

Jun 3, 2014

how to Delete Duplicates in Column D with a macro. It would search all of Column D and look for Duplicates and if it finds an exact value match it will delete one of the rows containing the duplicates. This is running in between a much longer macro which is the reason why I can't do it with conditional formatting.

Delete Duplicates In Column D?

Jun 4, 2014

I'm trying to create a macro that will Delete Rows of Duplicates found in Column D. It will start with the first row it finds that is yellow and check to see if that Column D matches any other yellow Column D's. If it does then the row the match is in gets deleted. Right now it searches in between the yellow rows, but for this portion I'm looking for it to use the yellow rows only. I included a file that has the examples on sheet1 and the expected outcome on sheet2.

Delete Duplicates In Column

Hi, the code in the codebox under here, which I wrote, is supposed to delete all duplicate records in the column. Which column to uniquify is stated in cell Skin!B17. I searched the internet round, and there are different solutions everywhere. I have been unable though to find the right one - so I thought, why not ask here. If you have a solution, I'd be happy to hear it ...

Normalise And Delete All The Duplicates

Jul 10, 2006

I am writing a spreadsheet to do the following. I have clients that submit lists of words (3 columns of data) that need to be normalised (ie - certain punctuation removing, casing to lower etc) and then all duplicates to be removed. It then pastes everything into a new sheet. Now, it all works perfectly but, runs a little too slow.

Sub NormaliseDedupe()
Application.Calculation = xlCalculationManual
Application. ScreenUpdating = False
Dim my_advertiser
Set my_advertiser = Range("G1")
Dim my_client
Set my_client = Range("J1")
Sheets("Normalised Keywords").Select
If my_advertiser = "" Or my_client = "" Then
MsgBox "Enter the Advertiser & Client at the top of the sheet."
Exit Sub
End If
Dim my_date As String
my_date = Trim(VBA.Format(Now(), "DD.MM.YY"))........................

Delete Duplicates Except Specified Values

Jun 20, 2008

I have a random set of numbers located in one column. This is the only data located on the entire worksheet. I need an Excel macro that will delete all duplicates except for any specified values. For example, I have a set of random numbers in one column and I need to delete all duplicates except for the number 12. All duplicates of the number 12 must remain. The numbers must remain in their original order and not be sorted.

The numbers will always be located in column A, but will not always be the same quantity. One time I may have 10 numbers, and the next I may have 20. The number for which duplicates must remain will also vary. I have written small Excel macros that delete rows, blanks, and duplicates but this is way beyond my capabilities.

Concatenate Cells And Delete Duplicates

Apr 1, 2009

I have an excel 2007 spreadsheet that lists
items on multiple rows for the same customer.

Each sheet will list anywhere from 25 to 100 individual customers.

I need to identify the duplicates, concatenate
the "Items" to a single cell on the first row, and
delete the duplicate rows. eg:

Cust #| Item
1 | A
1 | B
1 | C
2 | B
2 | E
3 | A
3 | C
3 | E

The result should look like:

Cust# | New Item
1 | A, B, C
2 | B, E
3 | A, C, E

Concatenate Duplicates + Delete + More Steps

Oct 15, 2009

I have 2 columns of data with 7,000 rows that I am trying to manipulate in the following way. The first column contains a list of car manufacturers (not really my example, but involves the same concept). The second column contains a list of different models of cars. For instance,

Ford | Taurus
Chevrolet | Avalanche
Saturn | Sky
Ford | Explorer
Honda | Accord
Ford | Taurus

What I want is a list of 2 columns with UNIQUE car manufacturers in first column with a list of UNIQUE car models (comma delimited) in second column. So for this example, the first row could read " Ford | Taurus,Explorer". I don't want Taurus to appear twice. I got a lot of help from JBeaucaire from this post. I just can't add the ability to remove car models from the list also. Thanks in advance for all the help!

Deleting Duplicates-Delete The Correct One

Apr 18, 2006

I have some Job numbers that are duplicates. I can't just do a loop and delete any duplicates that come across because I have to be sure the right one is deleted.

I want the old data to be deleted if there is a duplicate..I just don't know how to verify which one is the old one using VBA. I was thinking of maybe using an advanced filter, but I don't know enough about them.

Is there code that will check both duplicates and delete the old one?
