# Identify Duplicates Between 2 Columns Of Different Sheets

Mar 14, 2008

I have two spreadsheet in which I am looking for duplicate customer names.

1st - "Customers"
2nd - "Orders"

In column A of my Customers spreadsheet I have the following formula
=IF(ISERROR(MATCH(E2,Orders\$D2:D1000,0))=FALSE, "Y","N"). This allows me to see if a name in my Customer spreadsheet (column E is a field of names) is also in my Orders spreadsheet (column D is a field of names). My end results is either a Y indicating a duplicate or a N for no duplicates.

What I am looking to do next is to place in column B of my Customers spreadsheet the date that coincides with the duplicating customer name. Sorry to be confusing. If a customers name is found in the Orders spreadsheet I need to know what date has been given to this customer (column L in the Orders spreadsheet contains the date information).

However, on numerous occasions a customers name is found in the Orders spreadsheet more than once meaning there may be more than one date which needs to be placed in column B of my Customers spreadsheet.

## Identify Duplicates In Two Columns?

Jun 1, 2012

I have two columns of B2 and C2 data in the same worksheet and want to identify duplicates in the columns and return a value of true or false in column D. The formula I have been utilizing is:

=IF(ISNA(VLOOKUP(B2,\$C\$2:\$C\$5000,2,FALSE)),0,VLOOKUP(B2,\$C\$2:\$C\$5000,2,FALSE))

However, i receive a #REF# return in D. What am I missing ?

## Macro To Compare Two Columns And Identify Duplicates?

Jul 10, 2013

So here I have two columns Column 1 with repetitive values of some 10000 records Column 2 with unique values of 100 records I want to compare Column 1 and Column 2, identify the values in Column 1 that match with Column 2 and highlight them. Conditional formatting for duplicate values doesnt work because Column 1 has repetitive values.

## Identify Duplicates

Nov 9, 2009

I have two worksheets one worksheet contains Insurnace names and Addresses from a hospital. I need to match these up to specific Insurance codes from a billing company worksheet. The bad thing is my billing database has multiple duplicate addresses for different insurances (Yes this does happen where different Insurances have the same address-don't ask me why). So originally I did a VLOOKUP where I looked up the address from the hospital Spreadsheet and matched it to the Insurance Specific code. The pitfall to doing it this way is that it only grabs the first exact match from the Billing worksheet. Is there a way to either automatically identify the possible matches and allow me to choose which one is the exact match or how do I just identify duplicates on my billing worksheet and match them manually? I attached the worksheet.

## Identify Duplicates On Sheet 2 And Populate Number Of Duplicates On Sheet 1?

Apr 8, 2014

I'm trying to Count duplicate text on sheet 2 and populate the number of times repeated on sheet 1.

On sheet 1 I have A3:A128 and would like the number of times these respective cost centers are repeated in Sheet 2 to populate Column B of Sheet 1.

File attached.

Not sure which formula to use. I tried CountIF but didn't work with 2 sheets.

## Macro To Identify Duplicates

Jun 27, 2006

I am trying to write a macro to check for duplicate numbers. My logic is as follow:

If(A2-A3=0) Then
B3=1

I want to write the macro as follow:

Select Check>0
Do While Check <885
If(A2-A3=0) Then
B3=1
End If
Loop

## Identify Duplicates In A List

Oct 13, 2006

I need to identify duplicates in a list and have the foilowing formula:

=IF( COUNTIF(range1,A2)>1,"Duplicate","")

This works ok but i have a further condition which i dont know how to factor into the formula. I think i could write some vba to determine the dupes but i was hoping to avoid this as im sure it will take me an hour or so. Duplicates are identified at the moment as being identical numbers in column "amount", i now need to specify duplicates as being identical numbers in this range where there is at least one row with no pay date filled in in col "paydate"

## Identify Duplicates: Get A Unique List

Jan 12, 2010

I have a list of objects:

A
B
C
D
X
D
A
F
G
H

I know how to get a unique list. How do I identify those that are in the list more than once and how many times it is in the list?

## Identify Duplicates Across Multiple Colums And Rows

Dec 22, 2008

I have a spreadsheet with 20+ columns. Each column contains a list of invoice numbers, eg, 1234. The lists are all of different lengths (see below). I want to find a way to find/highlight/identify those invoice numbers that appear more than once in the entire sheet (eg if invoice 1234 is listed in column B, and also in column H, and/or if invoice 5678 is listed in column A, and also in column J, and also perhaps in column D, etc.)

I've searched this forum but haven't found anything about searching for multiple duplicates in multiple columns. Ideally the matches would be highlighted in different colours, (eg all cells that contain 1234 would be red, those that contain 5678 would be blue, etc., for ease of identification) but I'm not sure if that's possible. I've attached an example that I've shaded myself to show what I mean. I've tried the MODE function but that only tells me which invoice number occurs the most.

## Excel 2007 :: Identify Duplicates Within Same Cell?

Mar 30, 2012

I use excel 2007 and need a formula to identify cells that have duplicate values within the same cell. For example, some of my city fields have the city twice, like baltimorebaltimore.

## Review List Of Numbers And Identify Duplicates In Order

Feb 24, 2014

- I have a list of 8 digit numbers in Column A sorted small to large
- Some of the 8 digit numbers are duplicated.
- In Column B I would like to have more of a combination of countif and listing the duplicates in order (1 for the first dup in the column, 2 for the 2nd, etc.)

Example of what I'd like to see

Column A Column B
123456781
123456782
132546841
685036541
985413561
985413562
985413563

As you can see if the number in column A is on the list one time column B would show a 1If the number is shown two times (the first time it shows up will show a 1 the second will show a 2) If the number is shown 3 times (the first time it shows up will show a 1 the second will show a 2, the third tiem would show a 3)

## Identify The Errors, Duplicates, Typos And Such Between Two Spreadsheets Of Over 4000 Rows Of Data Each

Jun 29, 2007

I need to identify the errors, duplicates, typos and such between two spreadsheets of over 4000 rows of data each. The Macro: I got a macro working, but it's not perfect. So far, it can only tell data that's missing on spreadsheets A, or B. However, it can't tell which are the duplicates, typos, etc. Please look at the sample for more details. The code is included in the sample. And for your convenience, it's right here:

Sub difference_general()
Dim frontcount As Long
Dim backcount As Long
Dim diffcount As Long
Dim nosrcflg As Boolean
Dim front_ref As String
Dim back_ref As String
Dim anydiffflg As Boolean
Dim ftnotexistflg As Boolean
Dim invnotexistflg As Boolean
Application. ScreenUpdating = False
Application.Calculation = xlCalculationManual
Sheets("Diff").Select
Cells(1, 1).Select
Rows("2:65536").Select
Selection.Delete Shift:=xlUp
Cells(1, 2).Select............................

## Identify Changes Across 2 Sheets

Jan 24, 2008

I am looking for a way to search using macros. Currently i can search/find by cell, but i need to find with mulitple cells. An example is, sheet 1 "A2" and "B3" date needs to be compared to sheet 2 to see if the data is already in sheet 2. Column A is first name and Column B is last name. Need to know if that full name (first and last) is already in second sheet. I can already search for just the first name or just the last name but now the two together.

## Identify Sheets Having At Least One Formula Containing Cell

May 30, 2009

I am trying to loop through all the worksheets in active workbook. But I want to ignore all those sheets which does not have a single formula containing cell. I mean if the sheet has at least one cell with a formula then the loop should work on that sheet else ignore that sheet.

## Excel 2003 :: Identify All Sheets Related To One Sheet

Oct 13, 2011

I have been given an excel model to review;the workbook has 53 sheets. I would like to know if there is a way to create a flowchart/matrix with the relation of all the sheets. I would like at least to get a list of all the sheets related to each sheet. All what I was able to do is to get all the sheet names in one sheet. (I am using Excel 2003).

## Identify, List, And Sum 2 Columns

Apr 14, 2009

It's a time sheet that I need to have whatever data is listed in column E to be listed starting in cell C27 but only once even if it's listed several times. In cell D27 I need the sums to match the data to it's left with the values from above in column D. I've used fill colors to help show my intent. I would also like it to keep track of remaining vacation time by recognizing the word 'VAC' from column E and subtract the value from it's left. This value is shown in cell J26 as '46hrs REMAINING'.

## VBA / Excel - Identify Columns With More Than One Value?

Apr 9, 2014

I have a macro-routine that generates a table of all sheet-headers (+/- 100-120 sheets) in a workbook. It's crusial that all headers - row("1:1") - have the same values in respektiv columns -so I have this routine to check that this really is the case, before new prosess. The table is rather huge - so I should som way or another identify the columns with more than one value (f.ex back-ground-color in column-top-cell). In this case I must edit and correct the header, and run my routine once again - until all headers are the same

My routine works, but I dont know how to fix this mark-up stuff.

## Identify Multiple Columns In Listbox

May 18, 2007

The following code takes the selected item from a listbox and populates another listbox with the item. The problem is that only the item from column 1 is populated to the other listbox. How can I populate the other listbox with the items from both column 1 and column 2?

Private Sub cmdSelToExc_Click()
Dim i As Long
With Me.lstProducts
' Copy all selected items, then delete.
For i = 0 To .ListCount - 1
If .Selected(i) Then
End If
Next j
Next i
For i = .ListCount - 1 To 0 Step -1
If .Selected(i) Then
.RemoveItem i
End If
Next i
End With
End Sub

## Identify Blank Rows & Columns

Mar 19, 2008

What is the syntax that I have to use to identify whether or not an entire column or a row is blank? Specifcally I want some code where I can say if row 1 is null, or blank then delete the entire row or. if column A is blank then delete entire column

## Macro To Compare Columns A & B And Dispaly Any Duplicates In Columns C & D

Feb 21, 2009

what I'm after is a macro to check the contents of Column 'A' against column 'B' and display any duplicates in Columns 'C' & 'D'.

N.B. The headings of Columns C & D are :-

C = Value Found in Column A

D = Value Found in Column B

Any duplicate entries logged in columns C & D should be listed in C2,C3,C4....C20 and D2,D3,D4......D20 etc (in effect creating two new lists)

## Comparing Three Lists - Identify In 3 Separate Columns

Jul 9, 2013

I am working on a project, I have three different lists that I want to compare and I want to identify in 3 separate columns which titles are found on which list.

For example:

Title List 1List 2List 3
ACAROLOGIA x
ACCIDENT ANALYSIS AND PREVENTION x
ACROCEPHALUS x
ACS CHEMICAL BIOLOGY x x x
ACS CHEMICAL NEUROSCIENCE x x x
ACS COMBINATORIAL SCIENCE x x
ACS MEDICINAL CHEMISTRY LETTERS x x
ACS SYNTHETIC BIOLOGY x x x

## Identify MAX Value From Two Columns And Display Result In Other Column In Pivot?

May 30, 2013

I have a pivot table and perhaps that isnt the best way to do this. (Sample attached). Ultimately I need to display two columns only:

There are three columns of data.

There are multiple instances of the same application in ColA, ColB has usage =true or blank and ColC has multiple instances of the same business.

Based on the count of Application in ColA, and the count of Usage =True, I need to return the Business with the MAX count.

Note: the usage cannot be a filter, it must be a count.

## 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.

## Identify Which Rows Have Blank Values In Specific Columns?

Feb 19, 2013

I have a spreadsheet with columns and columns of data. What I'd like to do is identify which rows have blank/no data in all specified columns (H, K, O, S, U, W, and Y).

To clarify, I need to identify each row where all of these columns are blank (as opposed to each row where at least 1 column is blank).

## Identify Values Specific To Defined Groups Of Columns?

Sep 2, 2013

I have these kind of matrices (below) and I'd like to identify unique values specific to different groups of columns:

[Code] .........

For instance, in the example above, if we decide that A, B, C are "Group 1" and D, E, F are "Group 2", and that the values in rows 1, 2, 3 are independent (i.e., "x" in "1" is not comparable to "x" in "2", etc):
- In condition (row) 1: "x" is a specific value only found in Group 1
- In condition 1: "y" is a specific value only found in Group 2
- In condition 2: "x" is a value found in majority in Group 1
- In condition 3: no specific value can be associated to Group 1 or 2.

What I would like to get is a measure of whether:
(1) there are values over-represented in one of the groups, or 100% specific to one group.
(2) what are these values
(3) if multiple values are a bit tricky, then: what is the value which is the most over-represented in one group compared to the other (the maximum being 100% in one group and 0% in the other)

## Identify Minimum Combination Of Columns Which Makes Row Unique?

Nov 20, 2013

I have a (phylogenetic) matrix with a species in each row, and morphological character in each column, scored as 0, 1, 2, 3 or 4 for each different species, so something like the following but much bigger:

Character 1 Character 2 Character 3
Species A 1 0 1
Species B 3 2 2
Species C 1 2 0

I want to identify the minimum combination of different columns (i.e. their values, but also which columns) that make a particular row unique.

## Identify Duplicates And Their Corresponding Cells And Add Those Corresponding Cells?

May 19, 2014

So I have a list of numbers in column A with an amount in column B. There are duplicates in column A. I need those duplicates pulled out into another cell with its amounts from column B, then total the amounts from column B. This would give the user the total amounts from column B. I have attached a sheet with the examples hand typed.

## Macro To Identify Largest Value Across Columns - Then Subtract Value Held In Other Cell

Feb 18, 2014

I need a macro to identify the largest value across columns I2 - AS2. Once found, I need to replace the value with value found minus the value in BQ. The final step would be to highlight the cell that was changed across columns I2 - AS2, then move to the next row and do same until I reach the last row in the worksheet. The number of rows vary each day but the columns do not.

I have written the attached code, which identifies the largest value in the first row, but I don't know how to replace the value found with the new value and then move to the next row until it reaches the final row for the day.

In the attached file, my largest value sits in AC2. That value needs to be replaced with 486.17 (1,175.37 - the value in BQ2 of 689.20). The cell should then be highlighted so I can quickly identified what cells have been changed.

## Prevent Duplicates Between 2 Sheets

Feb 10, 2012

I have 2 sheets, List 1 and List 2 Both lists contain generic part numbers in column A, so because there could be 2 manfacturers of the same part there will be duplication of the generic part number.

What I want is to prevent someone entering a generic part number in list 1, which already exists on list 2.

I there any cde which can be put in the sheet which will show an error message for this?
