Many a times we require to compare two columns data and find out all the Duplicates. So in this article you are going to see how we can compare two columns in Excel and find out duplicates. There are two ways of comparing two columns in an Excel Worksheet. 1.By Using Excel Formula 2. By Using Excel Macro Compare two columns by using Excel Formulas: By using ISERROR and MATCH formula we can compare 2 columns.
Type the below formula in the column where you want the list of all duplicates in both the column =IF(ISERROR(MATCH(A1,$C$1:$C$5,0)),',A1) Where: A1 – Is the column Which you want to be compared $C$1:$C$5 – Is the Range which you want compared with. Compare two columns by using Excel Macro: 1.
This function will compare Column A with Column B and list the Duplicates in Column C in a Sequence. My problem is similar, but is about two comblist. My data base is A1:F1900 from this a:f I need to calculate all the gaps of each row first, and after generate a list with the same gaps, so the new list that I have in another sheet has to be compare and remove duplicates, and second from the a:f data need to calculate the differences by columns generate a list with this differences compare if this new list don't have the same interval with a1:f6 and again remove the duplicates from the other sheet. If somebody give me a hand in this, would be nice, is a real challenge.
Mathematical or logical operations cannot be done manually on Excel worksheets which contain large amounts of data, as it would take too long. But Excel is an efficient office software program that allows data to be automatically manipulated, through a macro or a VBA program code.To compare two columns and delete duplicates in Excel,a macro can be written to make a logical or mathematical comparison of the columns and remove the rows containing duplicate data.
A well-written Excel macro can accomplish the task quickly and accurately. It is easy to compare two columns and delete duplicates in Excel. Col A Col B Col C Col D 00001 AAAA1 xxxx yyyy 00001 BBBB1 xxxx xxxx 00001 BBBB2 yyyy yyyy 00002 AAAA1 yyyy xxxx 00002 AAAA1 yyyy xxxx 00003 AAAA1 xxxx yyyy Solution This solution will alter the data in your spreadsheet, so make sure you save a backup copy. Firstly, you need to combine the data in columns A and B so they can be compared as a whole. To do this, type into an empty cell at the end of the first row of data (in this example we are using row 2 - change as necessary): =A2&B2 Copy this formula down for the whole spreadsheet. Now run the macro below. In this sample code, it is assumed you wrote the above formula in column E.
Amend the code as necessary. Warning: This macro will delete rows, so it is important to make sure you have made your backup copy copy before testing it. Sub text Dim j As Integer, k As Integer, r As Range j = Range('E2').End(xlDown).Row For k = j To 2 Step -1 MsgBox k Set r = Range(Cells(k, 'E'), Cells(k, 'E').End(xlUp)) If WorksheetFunction.CountIf(r, Cells(k, 'E')) 1 Then Cells(k, 'E').EntireRow. Delete End If Next k End Sub Note Thanks to for this tip on the forum.
