Removing Duplicates Based On Several Columns

Aug 13, 2013

I have a list of about 85,000 addresses and I know that there are about 35,000 duplicates in it.

If I do 'Remove duplicates' it deletes them but takes the first one of each it finds and what I want to do is remove the duplicate with no UPRN in it (Column B)

Sorting Columns, Rows And Removing Duplicates

Dec 10, 2008

I have a single spreadsheet with a few columns but hundreds of rows. Each row is a property reference (with other data such as address in the columns) with a type of charge in column J and the amount in column K. I'll try to replicate below ...

A B ....... J K
Prop1 Prop1Address Rent 100
Prop2 Prop2Address Rent 150
Prop3 Prop3Address Gas 70
Prop4 Prop4Address Water 60
Prop4 Prop4Address Rent 200
Prop4 Prop4Address Elec 80
Prop5 Prop5Address Service 90

I want the sheet to display a property on a single row so would look like as follows ...

A B ....... Rent Gas Water Elec Service Total
Prop1 Prop1Address 100 100
Prop2 Prop2Address 150 150
Prop3 Prop3Address 70 70
Prop4 Prop4Address 200 60 80 340
Prop5 Prop5Address 90 90

Highlight Duplicates Based On 2 Columns

Oct 28, 2006

I have a column of information, and I want to find out of there are duplicates in it without alphabetizing it. Where there is a duplicate (say E2=E5), I want to check the adjoining column to see if the value of those fields are duplicates as well (does F2=F5). So, what formula would I put in D2 to see if the value of E2 has an equal anywhere in column E, and if any duplicates are found (say E10,E33, and E43), to check if F10,F33 and F43 equal F2 (the value adjoining the cell that was searched for).

to find duplicate entries in a database by using people's last names (in column E) and birthdays (in column F). Odds are if they have the same DOB and the same last name, we've found a duplicate.

Highlight Duplicates Based On X Columns

Aug 28, 2007

I need to find a way to highlight duplicate records within a list. The records would first need to be compared by (1) the month (found in column A), (2) the account number (found in column B) and then (3) the commission type (found in column D).

I do not need the duplicates deleted just highlighted or better yet maybe have them identified as "Duplicates" in an empty column (such as column H).

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 I’ve 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.

Indentify Duplicates In Table Based On X Columns

Nov 19, 2007

I have a worksheet that contains thousands of patient appointment entries, there are more than one entry with the same patient details contained in the worksheet. For example; sometimes a patient will reschedule a appointment, this causes another entry to added for the new appointment. When the patient attends this appointment, the appointment status changes to Seen. But the original entry still stays Rescheduled. This there a way that we can look for identical infomation in some selected columns that match the original entry but have different infomation in some other columns:

E.G. The cells in columns A,B,C,H have identical infomation than the original entry but the cell text in column D equals to "Checked" or "Cancelled" and the cell date in column G is higher than the original entry date. If the result is true then tag the original entry as Invalid

Transfer Duplicates Based On Matches In X Columns

I am working on a list of agents and I want to get rid of the duplicates. I know I could use conditional formating to highlight the duplicate names but it conditional formating won't allow me to find duplicates based on three cells in a row. My code below works to an extent but it misses some of the duplicates in the list and I don't know why. I have check the cells of the duplicates and they are an exact match.

How To Highlight Duplicates Based On Multiple Columns And Remove Them

Oct 8, 2011

I am trying to tell the spreadsheet that if column G *and* column V are both identical to another row's column G and V, then the entire row is a duplicate and to highlight and delete it. I also want to record a macro of this process to apply to all spreadsheets.

Here are the tutorials I am looking at, but whatever I am doing is not working the way it is working for them.

Conditional Formatting, find duplicates with multiple columns [URL]...

I am highlighting cell A2, and under Conditional Formatting, I select "Formula Is" =SUM(COUNTIF($G:$G,G2),COUNTIF($V:$V,G2))>1

Then I select the format as light orange text, but it is only highlighting A2....

That is as far as I have gotten, and I still do not know how to go about deleting the duplicate entries. I have also read there are issues with recording a macro when trying to find duplicates using more than one column in the formula, but I have not gotten that far so I can't test it.

As is likely evident in my formula and process, I am not very experienced with Excel.

Removing Duplicates With Less Elements In A Row

Nov 22, 2011

Writing macro for "Removing duplicates with less elements in a row."

I am trying to remove duplicate entries from a file based on the number of data present in a row. Please see below

Example:
Name Col-1 Col-2 Col-3 Col-4
abc 1 3 4
abc 1 2 3 4
abc
abc 1 4

I want to retain the row with maximum elements(row 2 in above eg.).

Result should be:

Name Col-1 Col-2 Col-3 Col-4
abc 1 2 3 4

Currently I am doing this manually, by adding countA at the end of each row, then arranging them in descending order. That will make sure that the row with more data comes first n hence gets retained, while other rows gets deleted.
Can this be done using Macro?

Below macro just deletes the rows,

Public Sub DeleteDuplicateRows()
Dim R As Long
Dim N As Long
Dim V As Variant
Dim Rng As Range

On Error GoTo EndMacro
Application.ScreenUpdating = False

[Code] .....

Removing Duplicates With Criteria

Feb 6, 2007

I'm adding data from a report into a spread sheet and some of it will be duplicated. I want to remove the duplicate data, but is there a way to differentiate between the older (and more complete) data and the newer data? In other words, how do I get rid of the duplicate while keeping the one I want to keep?

I was considering the advanced filter, but if I create too many columns of criteria will it be seen as unique?

Rule For Removing Duplicates In Data?

Jun 10, 2014

I'm trying to find out the rule for de-duplicating data. I am removing duplicates based on an identification number in a data set of about 6000 records, including the duplicates (some records appear about 4 times). Due to the nature of the data I'm working with, there are only a handful of records that are "true" duplicates, i.e. some of the records appear 4 times but there is a difference in terms of location, etc and some are true duplicates in that there is no difference.

I need to know how Excel removes duplicates - does it only keep the first line that it finds for that identification number? Also, is there a way that I could create a rule for it to keep the record with the highest rate for example?

Removing Duplicates Feature Is Malfunctioning

Mar 13, 2009

i'm trying to remove duplicates from a worksheet containing customer contact info. the sheet has 9 columns with headings, and the duplicates appear in the last name and phone number column. (the sheet contains no outlines/groups/subtotals.)

i want to remove entries that contain the same last name AND phone number, however when i go to DATA>DATA TOOLS>REMOVE DUPLICATES, and specify the columns i want to remove duplicates from, it keeps deleting an entry that has the same last name, but not the same phone number.

i even tried removing duplicates from only the phone number column, and it still removes the phone number for the entry that has a duplicated last name, even though the phone numbers are different.

Removing Duplicates From Long Row Of Data

Mar 12, 2014

I have several fields in a row that contain names of files e.g. 123.xlsx. Some fields will contain file names that will be duplicates of each other and some will be blank entries (although the blank entries can be changed to a value such as 'n/a' or 'no' etc if required).

I require only the non duplicate values to appear in the final cell, each separated with ';'.

My data is in row 2 of a spreadsheet and in every other column (A,C,E,G,I,K,M...for 45 instances in total).

I have used the following formula to identify the unique values (example below for the first four cells):
=A2&IF(C2=A2,"",","&C2)&IF(OR(E2=A2,E2=C2),"",","&E2)&IF(OR(G2=A2,G2=C2,G2=E2),"",","&G2)

This works well and if there are several blank entries then I use a SUBSTITUTE function to change the multiple ',,,,' to a single ';'. So I only see the unique file names in the final cell, separated with ';'.

However, the above formula becomes longer and longer when each cell is added to it. I have over 40 cells that need to be added and I wondered if there was a better way of doing this?

Is there a way to add this new data (ActiveList.xlsx ) to the last row of data of my (UpdatedMembers.xlsx) Sheet and remove duplicates. (I would like the new additions to stay on the bottom of my original data in the UpdatedMembers sheet, so that I can add notes to their row)

Removing Duplicates In One Column And Summarizing Data

Feb 9, 2012

I have a 5 column document with about 3000 entries that I need streamlining. THe first column is a student's name, then grade. The next 2 columns are for Honour Roll Standing (A or B) and/or an Effort Honour Roll Standing (E). Finally there is also a "term" column indicating if they received this award is Term 1, 2 or 3.

An example source file is found here: [URL]...

As you can see, there are many students who have received an award in all 3 terms, however there are also some students that only received standing for 1 or 2 terms.

I need to manipulate the data so that there are no duplicate names and all the data regarding Honour Roll standings and which term it occured in are all laid out in one row per student.

IDEAL COLUMN HEADINGS:

NAME | Grade | Term1 HonourRoll | Term1 Effort | Term2 HonourRoll | Term2 Effort |

etc etc etc
