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.

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)

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 ?

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.

I have column A that is 1,500 records.
I have column B with 40,000 records.
Among the 40,000 records in column B, duplicates of ALL 1,500 records from column A exist.
My question is: How do I find WHERE the 1,500 dupes are and how can I delete JUST those records?

Columns A, B, and C have data (first name, last name, state) - 125k rows. Columns F, G, and H have data (first name, last name, state) - 5k rows. Some of these individuals are bound to appear on both lists, and I need to know which ones are indeed on both lists. So in other words, let's say I've got "John" "Doe" "TX" in cells F1, G1, and H1, respectively. I want to search through columns A, B, and C to find out if there are any instances in those columns of "John" "Doe" "TX" in the same row.
I'm thinking there will be multiple VLOOKUP formulas involved, but I could be way off.

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.

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.

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.

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"

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.

- 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)

I am having no success using either: 1) COUNTIF with wildcard (*) or 2) Case Statements to find text strings in a cell. I've even tried using Copy/Paste Special values to change the way Excel 2007 interprets the field.
The Do While loop looks at target cells in Col. 18 which contains one or more specific last names. I want to put a text string (also a name) in Col. 19 IF the target cell contains the last name in the COUNTIF or Case Statements. The COUNTIF normally puts a TRUE or FALSE based on the condition, but I'd like to put the the last name based on which condition is met and then continue looping to Row 3. It's a small number of rows, less than 100.
Here's the Case statement ...

My Process goes like this: We receive work in the excel sheet and in the column K(Period will be in YYYYMMDD)
First I want macros by which I can change YYYYMMDD TO MMDDYY.
then
It should compare column J and column K.
see the below example.
Period date (column K) Product end date (column L)
Column J column K
20131031 10/31/2013 = If column J & K dates are equal then "No action required"
20131031 7/31/2013 = If column J is higher then column K dates then "Action required"
20130930 11/2/2013 = If column J is lesser then column K dates then "No action required."
I need comments in column Q.

Shaffer Kerry
Sheet 2
Last Name First Name Match No Match
Klee Pierre X

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............................

I am trying to modify the macro listed below for the following example. It would work when I have only numerals in the cell but this new query, the cell has both letters and numbers.
I want to compare column "M" from worksheet one to column "B" in worksheet two. If the information matches, then copy the value adjacent from worksheet two column "A" to worksheet one column "L".
Here is the macro that worked for me using a search of only numerals.
figuring out why the data doesn't copy?
Macro:
Sub merge_accession_PS_rad_productivity()
Dim rng2 As Range, c2 As Range, cfind As Range
Dim x, y
With Worksheets("Imaging_Summary")
'N4=Accession on Imaging Summary worksheet
[Code]....

I am trying to create a macro that will compare several un-formatted workbooks and copy just what I want to a workbook of my one.
I start by having 2 different workbooks opened ("Main" and "Change") side by side like this: 1.jpg
Then i run the macro in my "Main" workbook and it should appear an Userform like it showed in the image below: 2.jpg
This is so that i can manually fill the user form with the correct columns by looking at the excel file, for example:
Ref=E3;City=G3; Data=I3.
Pressing Ok, it fill the "Main" workbook with the matching information so it and closes the "Change" workbook.
At the moment my code is in this stage:
VB:
Private Sub CommandButton1_Click()
myfile = "C:Userssst1brgDesktopRelatorios" & TextBox1.Value
Application.Workbooks.Open Filename:=myfile
Windows.Arrange ArrangeStyle:=xlVertical
[Code] .....
But I am stuck because there isn't any error and nothing happens.

I receive a daily spreadsheet which contains (amongst other information) a column of postcodes. I'd like to run a macro which compares these postcodes with a list of other postcodes, and then to colour highlight each instance of that post code in the daily spreadhseet.
I have been able to find and modify a macro but that searches for one post code at a time and then adds a comments box to the cell.
Instead of copying that piece of code and editing it for the several hundred post codes I need to "look up" against, I'd like to know how to create a list of post codes in the macro, so that the macro searches the first post code in the lookup list, finds and highlights each cell instance, then moves onto the next post code in the lookup list, until the end of the lookup list. I would like this as the editing of the lookup list would be much easier than editing paragraphs of code.
