How to find duplicate values in two columns in Excel?

When we use a worksheet, sometimes we need to compare two columns and find the same values. For example, I have two long columns of student names, and now, I want to compare them and find out the same names. If I compare them cell by cell, it will be tiresome and waste a lot of time. Are there any quick ways to finish this task?

Find duplicate values in two columns with Formula

Look at the following screenshot, I have column A (A2:A15) and column C (C2:C13) which contain some duplicate names.

doc find duplicates 1

By using a formula, we can compare two columns and display the duplicate values. Please do with the following steps:

1. In cell B2, input this formula: =IF(ISERROR(MATCH(A2,$C$2:$C$13,0)),"",A2).

doc find duplicates 2

Note: In the above formula: A2 is the column which you want to be compared. $C$2:$C$13 is the range that you want to be compared with. You can change the variables for what you are using.

2. Press the Enter key. Select cell B2, and then drag the fill handle over cell B15. And all of the duplicate names will be displayed in column B. See screenshot:

Find duplicate values in two columns with VBA code

Set Range1 = Application.Selection
Set Range1 = Application.InputBox("Range1 :", xTitleId, Range1.Address, Type:=8)
Set Range2 = Application.InputBox("Range2:", xTitleId, Type:=8)
Application.ScreenUpdating = False
For Each Rng1 In Range1
    xValue = Rng1.Value
    For Each Rng2 In Range2
        If xValue = Rng2.Value Then
            If outRng Is Nothing Then
                Set outRng = Rng1
            Else
                Set outRng = Application.Union(outRng, Rng1)
            End If
        End If
    Next
Next

Application.ScreenUpdating = True
End Sub

      Taher... Send me your Email ID. I can help you. What i understand that you have 2 sheets. One has names and some Code for each name and the second one has Addresses and Codes. The Code is the only column which can connect these 2 sheets. And you want all the names and their corresponding addresses to be displayed based on Codes.

      Please send the same question to my email id vijkid143@gmail.com. I can send you the script and tell you the steps how it works.

      Regards

    I'm trying to compare values on two columns on the same spreadsheet. Where there are duplicates, that is fine. However, where the values differ, I want the contents of one of the columns to be replaced with that of the other column. How do I go about that?

    Hello,
    Is there any way to [u]match & pair [/u]duplicates in two separate columns? Example: There are 6 identical search items being searched for and only four identical amounts in the column being searched.
    The match function finds the 1st duplicate in the column being searched and then returns the ordinal location of that 1st match position for each subsequent duplicate it finds in the search column.
    Is there any way to identify duplicate matched items & define their distinct ordinal position with the column being searched.
    This way if there are six duplicate search item amounts and only four duplicates found in the "Search Column" only the four items in the "Search Column" are matched and paired with the items searched.
    I hope I have explained myself clearly and would like to thank you in advance for any help you may be able to offer on the subject.

    Kind Regards,
    RWF

    This article shows how to highlight duplicate values across a number of columns, however it is looking for duplicate values within each column. I was hoping to highlight cells when the value in the 1st cell in column 1, equals the value in the 1st cell in column 2, and the same all the way down. So if A5=B5 I want it to be highlighted, but not highlight if A5=B6, and not highlight if A5=A6. I hope that makes sense. Is there a way to do this?

    Sadly, this didn't work for me. I have literally copied and pasted the formula, so I don't know why it didn't work.

    I have experimented with making my data text, numbers, or general.

    All I get is the formula displayed. The formula actually isn't performing its function.

      There is another way · 3 years ago
      You can also use the Match function.

      Make sure to put your headers so you can also sort after
      In column A you have 1 list and in column C your 2nd list
      In B2 use Match(A:A,C:C,0) hit enter.. it won't work if your items aren't matching in what they are, like a number to a number thing
      Then using your filter function uncheck everything except the N/A in the 2nd column and you will see what isn't in the 1st.. easily knowing what didn't have matches and what did. You can do it both ways so just reverse the C and A in the above formula and see what isn't in A that is in C.. It works great for really long lists, then you don't have to continually scroll for those with and without matches.

      Suggestion to Ian - when copy/pasting from a website to Excel, first copy to Notebook and then to Excel. Sometimes the formatting of the text in the website is what is screwing it up, by sending it through Notebook first you are removing any and all formatting.

        I did this, but it still will not work. If I find a duplicate on my own and cut & paste that cell from column c to a. THEN the formula Shows me. ALL cells are Formatted the same. Why is it doing that?
