Compare 2 Columns And Remove Dups
Feb 15, 2009
I have 2 columns of data (1 of 7000 and 1 of 39000). First column of 7000 entries should all be in the second column.
Example:
Record OLDRecord NEW
DBE2008/49IEP2007/0032
DBE2008/48IEP2007/0033
DBE2008/47DBE2008/47
DBE2008/46DBE2008/44
DBE2008/45RIE2008/0212
DBE2008/44TK2004/0073
DBE2008/43ID92/0522
DBE2008/42ID96/0274
IEP2007/0032DBE2008/41
I would like to compare these 2 columns and remove the 7000 entries from the second column. This can either be removed from the second column or resulted in another column. I am only quite new to Excel and formulas

I tried using several of the formulas and VBA codes from other posts, but they just didn't work out quite right. And since I'm worthless at VBA coding, my changes either did nothing, ruined the code entirely, or blew up my computer : D . The attached doc should explain everything.

I've been searching for a method to compare two large columns of numbers and remove replicates from the "main" column. Column A has all the numbers that are in column B and many more. I want to remove all the numbers from column A that are in column B. The result being two columns with no matching numbers. (or a third column that has only the numbers from 'A' that are not in 'B').
My search results on this forum have found results that compare rows for matches & can make deletions; and also one method that could mark all the entries that were duplicates in both columns, but nothing to remove them. The datasets I am using have over 400k entries in some columns, so manual removal of marked ones is not feasible. I need an automatic deletion method.

I'm trying to find some vba code that will find dups on my worksheet and highlight them in a special way: first dup = bright yellow, second dup = bright green, third dup = bright red, and if there is a forth, fifth or sixth dup, then just increment color number to next one, than next, etc...
I would like for the code to run as soon as there is a change on the worksheet (when I finish entering data in a row). I think I already have the right code to do that:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Range("E9:E10000")) Is Nothing Then
Call dupSearch
End If
End Sub
I tested it out, seems to work as it should.
My major problem is that I need the code to check column F9:F10000 and compare the cells all along that column. That column concatenates 3 other cells in that same row (lastname&firstname&employee#), so if I run my dupSearch on that column only, I should find only real dups, and not just 2 people with the same name.
I also need to make sure it doesn't find empty cells, thinking they are dups. I would like to highlight column A to E of the row that contains the dup, and not just the cell in column F.
I have tried many other codes that I have found on the forum, but none of them work right with what I'm trying to do, and I just don't know enough VBA to make the changes I need.

The following code compare two sheets and remove the duplicate rows to a new sheet. In this code I have to create the third sheet manually.
I need the "New Sheet" to be create automatically with the name of "Dup".
Code:
Option Explicit
Sub nomatchnoty32()
Dim X, i As Long, j As Long, Y(), Dic As Object, k&, Z, name1$, name2$
Const shSource1 As String = "sheet1"
Const shSource2 As String = "Sheet2"
[Code] .........

I'm trying to compare values in 2 separate columns to see how many times the same value appears in both columns. Ideally I would be able to insert a range function to compare the values in the column "ID 1" against the values in column "ID 2" and return the count of times that a value appears in both columns. For example 2122, 1112 and 1718 appear in both columns and I would like the formula to return a count of 3.
ID 1ID 2
12342122
45671112
89101718
11122678
13144544
15162324
17189987
19201215
21221928
1976
2576
2345
4678

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)

Using the following code to remove empty rows based on whether a specific range of columns is empty. The code works if the cell has a zero, but not when the cell is blank. An example of the data is attached.
VB:
Public Sub DelRows2()
Dim Cel As Range, searchStr, FirstCell As String
Dim searchRange As Range, DeleteRange As Range
[Code].....

i've check the other threads on how to compare two columns but for some reason it is still not working for me.
I have 2 columns. Column A is the master column and column B is the comparing list. If the company that is listed in Column B (Anywhere in column B) matches exactly with the company name in column A, I would like it to say "check" in column C.

I need to compare two columns A and B with a result in column E. BUT I don't want the result to be added together. ( since it's receipt numbers ) SO my formula is incorrect I need a formula that will show the receipt numbers next to each other divided by a comma or forward slash...

I can find lots of ways to compare two lists with single columns, but I need a very basic guide to comparing multiple ones across two sets of data and then highlighting or extracting the unique records. I would prefer to keep the data in the existing columns for later sorting and other purposes.
I currently have the two datasets as two separate worksheets in an Excel 2003 file. The two datasets consist of the same three columns containing strings of text, but there is quite a difference in the number of rows. Dataset One is c. 3550 records, Dataset 2 is c. 1600. There are no duplicate records within each dataset, but there are duplications across the datasets and the records are in a different order, so it's not a matter of comparing Row 1 to Row 1 and so on. The data look a bit like this (semi-colons to show columns):
DATASET 1
Group;Family;Name
PM;Smith;Mary Anne
PM;Jones;Fred Henry
PD;Wilson;Peter John
PG;Green;William Laurence
...............

I need a Vlookup to look at two columns when searching. here is an example:
Sheet 1 is my report grid to hand out to the employees, A1 has a drop-down list with my employees names and A2 one for the month, when you click an employee name the vlookup formula fills in the information from sheet 2 (data sheet).
Sheet 2 has data like: Col 1= Month, col 2=employee L-name, col 3= production etc...
currently the vlookup formula messes up because the employee name is in there multiple times because of the months column, i have to delete all months except the one i need. formula is: =vlookup(A1,'sheet2'!,B:C,2,false)
this formula will pull the data in sheet two column 3 (production) for the employee that matches.
how can i make it compare first to col 1 (month) and then col 2 (employee).

I want to compare many columns and find duplication in the last one;
Example:
Column A Column B Column C Column D Column E
1234 1234 1 A OK
1235 1235 1 A OK
1236 1236 3 A OK
1237 1236 0 A OK
1238 1236 1 B Duplication found in different column
1239 1238 0 A OK
To get Column "C" which is calculate how many numbers in that row are repeated with respect to Column "B", I solve it by using : =COUNTIF(B:B,A2) ;
But I want to get a result of duplication in "Column E" by see if "Column B" + "Column D" has the same value regardless of number then say "OK", but if it is not than the before, then write "Duplication found in different column".

The code below compares values on sheet 4 column A to sheet 3 column A and then colors a cell "Green" (Temporary), later I will place data from sheet 4 into sheet 3.
I dont know why but when it finds data on sheet 4 that is not 100% numeric it errors out.
Run-time error '91'
Object variable or With block variable not set.
The data in sheet 4 column A is primarily numeric, there are and always will be some numeric/alpha strings.
I can change the value of sheet 4 A2 to "123x" from "123" and the code stops as described. Leaving sheet 4 A1 as 100% numeric, which works fine.

i'm trying to do some analyzing on an excel sheet and was seeing if there was a function that I could use to speed this up.
So in the file...
I want to Group what's in Column A So the 1's together and the 2's together... Once that is selected I want to know what the largest number in Column C is...
So if the function can select 1 in column A then tell me that 10 is the biggest number in Column C....

I would like to have a macro or a function, which could compare two "A" columns in different workbooks. macro should run from the first one wb, which gonna have less data in a column than wb2. so, if, let's say, A3 in wb1 differs from A3 in wb2, an empty row should be added in wb1, and now we would jump and compare A4 in wb1 with A4 in wb2 and so on..

I have an excel spreadsheet with multiple columns of options.
In column A, I select either "yes" or "no" to activate other columns.
In column B, I have, let's say, lease terms; 12, 24 & 36.
I'm trying to find a formula that I can enter that will take all the columns I select as yes, and tell me if the lease terms match up.
So, if I select yes in cells A4 & A13, are the lease terms in B4 & B13 the same...do they match?
