Establishing Duplicate Entries - Highlighting Them Then Deleting

Apr 17, 2014

I have a spreadsheet with thousands rows of items on. I am trying to identify duplicate entries based on two or three cells within each row. If those two or three cells are duplicated for that particular ID then the duplicate entry (row) should be highlighted for deletion.

Better still it would be great if there was a macro or formula which would delete that duplicate row.

So for example on the spreadsheet I have attached, I would like rows 6 and 9 deleted or highlighted as the criteria for deletion is a duplication of the entry in the 'YEAR' column AND the 'VALUE' column for the REFERENCEs AB-1234 and AB-9876 which are the unique identifiers for each individual case.

This would leave the end result as per the table below on the attached spreadsheet.

Highlighting For Duplicate Entries

Nov 24, 2009

I would like to check column B and if any of these values match values in column J hightlight the cell on the same row as the match on column E green. I don't know much about excel but this would be a tremendous help because i'm looking through quite a bit of data. I've tried using conditional formatting and i can't seem to get that to work for my needs. Let me know if you need anymore information.

Highlighting Or Deleting Specific Cells

May 16, 2009

I have Column A with 380 cells filled in with numbers (A1-A380) i.e. numbers like..456758, 567848 etc etc

Column B has a subset of those numbers, maybe 80-90 or so (B1-B90).

What I want to do is either highlight the numbers in Column A that also appear in Column B in yellow, OR delete them from Column A altogether

Highlighting Duplicates Entries Across Specific Sheets

Jan 20, 2012

I have 13 sheets of data in my open workbook. Column D, which includes blank cells at times, across each of these sheets maps the same info. of orders. However, I know there are several duplicates, and I want to clean them out. I am trying to figure out a way to highlight all the duplicates that appear only in column D beginning with sheet 4 and ending with sheet 13. I will leave the duplicates that appear on Sheets 5-13 alone, but I want to have them highlighted, so I can review the ones that appear on sheet 4 first, and then delete them.

Highlighting/Deleting Special Charahters In A Range

Aug 15, 2008

I have a column that needs to be text format, but it needs to include only digits (0-9), no letters, no special characters. Also all cells need to have 7 digits.

I am trying to do a couple of things:
1 : Hightlight the cells that contain Strings with Non-Digits characters
2 : Highlight the cells with less than 7 characters (I have the code, it is below)

I have tried many ways to get #1 but I am stuck.

Help please.

This highlights the cells with less than 7 characters:

Sub StringLength3() ' IT WORKS!

Dim strTest As String
Dim i As Integer
Dim Cell As Range

'Select Range
Worksheets("tres").Range("A2", Range("a65536").End(xlUp)).Name = "RangeA"

For Each Rangea In Selection
i = Len(Rangea)
If i 7 Then
Rangea.Cells.Interior.ColorIndex = 7
End If

Next Rangea

End Sub

Highlighting All Duplicate Values Except First Instance?

May 22, 2014

I need to highlight all the duplicate IP-addresses in my sheet except the first one.

What I did:

I chose the range (F column) -> Conditional formatting -> Highlight cell rules -> Duplicate Values. It highlighted all the duplicate values so i googled how to highlight the duplicate values except the first one so I came across a formula =COUNTIF($F$2:$F2, F2)>1

So I added the formula and now it does not highlight the first duplicate but only the second and not the third and fourth and so on.

What am I doing wrong?

Edit: I have sorted them in order and in one IP-address I have 6 duplicates but it highlights only the last one when I want it to highlight all of them except the first one.

Highlighting Duplicate Data In Column Across All Cells?

May 17, 2014

I have a large compilation of data on an excel work sheet (I am using 2013). All cells relate to each other by means of dates, names, and other numeric values such as stock numbers, id numbers etc... In one column some stock numbers are repeated. I would like to know if there is a way to set up the program on this worksheet to highlight all repeating stock numbers, not only in the column but across the cells as well, in lieu of doing so manually.

Deleting Old Entries

Dec 16, 2009

The following code works fine if the data is grouped (not necessarily sorted) by column B (but not necessarily by column A), this code will delete the duplicates rows, but retaining the latest entry (by column A) of each name in column B.

Sub DeleteTheOldies()
Dim RowNdx As Long
For RowNdx = Range("B2").End(xlDown).Row To 2 Step -1
If Cells(RowNdx, "B").Value = Cells(RowNdx - 1, "B").Value Then
If Cells(RowNdx, "A").Value

Duplicate Entries

Sep 24, 2009

I have been trying a number of different functions!

I have the following countif function that is searching a worksheet (Cases Closed) for the name John in Column O and excluding Solutions in column x. The problem I have is there are duplicates cases in Column C that are being counted two and three times.

Is there anyway to have the following function exclude duplicates records in Column C? Just count unique records in Column C?

=(COUNTIF('Cases Closed'!O:O,"John"))-(COUNTIFS('Cases Closed'!O:O, "John", 'Cases Closed'!X:X, "*Solution*"))

How To Combine Duplicate Entries

Apr 23, 2013


Basically I've made this up myself because what ill be working with has 100s if not 1000s of rows with many different product numbers that's quantities are different. What I've been able to do up to now is sort the spreadsheet by the product number so all the same rows are next to each other. My problem is however I need a speedy way of making these duplicate rows become one but add the total quantity basically everything in the left screenshot into the one on the right. What I've tried up to now is sorting them so there together and manually adding them up and putting them into one of the rows quantity, then delete the rest. takes to long. Another was to make a row underneath the rows I need into one but that takes more time than manually adding and deleting the rest.

Clear Duplicate Entries

Jul 14, 2008

I am trying to find a macro that will clear duplicate entries in a column of data, and then move to the next column and repeat the process until it gets to a blank column.

There are blank cells between entries in a column. I need to keep the data unsorted as the cells are linked to others in the row, therefore I dont want to delete the cells, just clear the contents.

Eliminate Duplicate Entries WITHIN A Row

Feb 8, 2010

I have a table of data like this:

A , 1 , 1
B , 2 , 1
C , 3 , 4
D , 1 , 3
E , 3 , 3

I need to eliminate duplicate entries WITHIN a row. So, I need the table to become:

A , 1
B , 2 , 1
C , 3 , 4
D , 1 , 3
E , 3

Is there an easy way to do this for a large sample? Also, there are actually more like 8 columns of this data, if thats important.

Preventing Duplicate Entries

Dec 11, 2012

I've generated a sheet where, based on the total run hours of a generator set using a given fuel type, we can determine which engine to run on what fuel when. The problem I've run into is that if more than one engine has the same runtime, the chart returns just the lowest numbered engine and eliminates the remaining engine(s). What I'm trying to do is make it so that when this occurs, the suggested engines show up in numerical order. For example instead of 1, 1, and 1 showing up on the chart, something like 1, 2, and 5 will show when they all have 0 run hours. I've attached my chart below with some engines having the same runtimes. RunOrder.xlsx

Stop Duplicate Entries In A Row

May 25, 2009

however I don't know how to change that to suit my needs (or even if it is at all possible to change it to suit my needs)

I will try my best to explain how my spreadsheet is set up as unfortunately I am at work and I can not use the method to show you the spreadsheet.

My spreadsheet:
I already have Data Validation in use from a list that I created. I use the same validation list in Columns C, E, G, I, K-BA

I also use validation list in other cells, and it is OK if these are duplicated throughout the row.

The only cells that should not contain duplicate information are the ones from C, E, G, I, K-BA

Basically I want to stop someone accidentally chosing the same option from the list within the same ROW.

Just in case it makes any difference I should let you know that I have already had help from the forum regarding macros for this same spreadsheet, here is the macro that is currently running just in case it makes a difference if there is an answer to my current problem.

Option Compare Text 'A=a, B=b, ... Z=z
Option Explicit

Private Sub Worksheet_Change(ByVal Target As Range)

Dim Cell As Range
Dim Rng1 As Range

On Error Resume Next
Set Rng1 = ActiveSheet.Cells.SpecialCells(xlCellTypeFormulas, 1)
On Error GoTo 0
If Rng1 Is Nothing Then
Set Rng1 = Range(Target.Address).........................

Duplicate Entries, Validate Only One

Jan 22, 2007

In my spreadsheet, on ( sheet A) I pick up a value to a range (O2:O22) from other worksheet (sheet B), the value is validated when a cell in the same range but other column (A2:A10) reach a specific criteria.

But in the same column if the criteria is typed again I gone a have the same value on range( O ), and I dont want that, because this value represents a total for a day, and is to be added to other cell.

I'm using this, to pick up the data
(A2:A10) Criteria
(O2:O10) value picked up

on SheetA, Sumif(sheetBA10:A40,A2,SheetBK10:K40)

How can I count only one of the values picked up from sheet B?

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

EG 111 in (A) & 222 in (B) are a PAIR, im need an if statemnet in Column (C) to say if this PAIR are duplicated in these two columns return "YES". I have tried THREE different methods to do acheive this which are in the attached document. The main issue I am having is the iff statement is returning yes for some of the number when thye are completely different. I have used concatenate, & and tried to multiply the two values to try to make it unique. I have an example of each in the separate tabs.
