## How to concatenate cells if same value exists in another column in Excel?

Author: Siluvia Last Modified: 2023-04-23

As shown in the screenshot below, if you want to concatenate cells in the second column based on the same values in the first column, there are several methods you can use. In this article, we will introduce three ways to accomplish this task.

#### Concatenate cells if same value with formulas and filter

The following formulas help to concatenate the contents of the corresponding cells in a column based on the same value in another column.

1. Select a blank cell besides the second column (here we select cell C2), enter formula =IF(A2<>A1,B2,C1 & "," & B2) into the formula bar, and then press the Enter key.

2. Then select cell C2, and drag the Fill Handle down to cells you need to concatenate.

3. Enter formula =IF(A2<>A3,CONCATENATE(A2,",""",C2,""""),"") into cell D2, and drag Fill Handle down to the rest cells.

4. Select cell D1, and click Data > Filter. See screenshot:

5. Click the drop-down arrow in cell D1, uncheck the (Blanks) box, and then click the OK button.

You can see the cells are concatenated if the first column values are same.

Note: To use the above formulas successfully, the same values in column A must be continuous.

#### Easily concatenate cells if same value with Kutools for Excel (several clicks)

The method described above requires creating two helper columns and involves multiple steps, which may be inconvenient. If you're looking for a simpler way, consider using the Advanced Combine Rows tool from Kutools for Excel. With just a few clicks, this utility allows you to concatenate cells using a specific delimiter, making the process quick and hassle-free.

Tip: Before applying this tool, please install Kutools for Excel firstly. Go to free download now.

1. Click Kutools > Merge & Split > Advanced Combine Rows to enable this feature.
2. In the Advanced Combine Rows dialog box, you just need to:
• Select the range you want to concatenate;
• Set the column with the same values as the Primary Key column.
• Specify a separator to combine the cells.
• Click OK.

Note:

#### Concatenate cells if same value with VBA code

You can also use VBA code to concatenate cells in a column if same value exists in another column.

1. Press Alt + F11 keys to open the Microsoft Visual Basic Applications window.

2. In the Microsoft Visual Basic Applications window, click Insert > Module. Then copy and paste below code into the Module window.

VBA code: concatenate cells if same values

``````Sub ConcatenateCellsIfSameValues()
Dim xCol As New Collection
Dim xSrc As Variant
Dim xRes() As Variant
Dim I As Long
Dim J As Long
Dim xRg As Range
xSrc    = Range("A1", Cells(Rows.Count, "A").End(xlUp)).Resize(, 2)
Set xRg = Range("D1")
On Error Resume Next
For I = 2 To UBound(xSrc)
xCol.Add xSrc(I, 1), TypeName(xSrc(I, 1)) & CStr(xSrc(I, 1))
Next I
On Error GoTo 0
ReDim xRes(1 To xCol.Count + 1, 1 To 2)
xRes(1, 1) = "No"
xRes(1, 2) = "Combined Color"
For I = 1 To xCol.Count
xRes(I + 1, 1) = xCol(I)
For J = 2 To UBound(xSrc)
If xSrc(J, 1) = xRes(I + 1, 1) Then
xRes(I + 1, 2) = xRes(I + 1, 2) & ", " & xSrc(J, 2)
End If
Next J
xRes(I + 1, 2) = Mid(xRes(I + 1, 2), 2)
Next I
Set xRg = xRg.Resize(UBound(xRes, 1), UBound(xRes, 2))
xRg.NumberFormat = "@"
xRg = xRes
xRg.EntireColumn.AutoFit
End Sub``````

Notes:

1. D1 in the line Set xRg = Range("D1") means that the result will be placed starting with cell D1.
2. "No" and "Combined Color" in the line xRes(1, 1) = "No" and xRes(1, 2) = "Combined Color" are the headers of selected columns.

3. Press the F5 key to run the code, then you will get the concatenated results in specified range.

thank you very much, the VBA code works very well but I have a question that I can't solve.

NO Color
1 red
1 blue
1 red
1 yellow
2 red
2 yellow

in this case, in column B we have some duplicate colors related to the same number. How can I have an output that only return the values once?

I would like an output like this

NO Color
1 red, blue, yellow
2 red, yellow

Hi

The second method described in the post can help you solve this problem. After following the steps to specify the settings, checking the Delect Duplicate Values option will delete all duplicates in the combined results.

Hello, the macro above works great! Thank you. Is it anyway possible (I tried, but not successful) to amend it to concatenate column B (description) based on duplicates in column A (HS code) but also taking column C (origin) in the combination?
So description texts concatenate per HS code per origin.
Also column D(quantity) and column E(value) must be summed per HS code and origin.

A B C D E
HS CODE DESCRIPTION ORIGIN QUANTITY VALUE

Hi Ivar,

Thank you for your comment. I am not able to solve this problem with VBA code yet. Sorry for that.
You can try if the last method can help.

Hello, how would the VBA code be adjusted if I want to combine cells in column M based on the duplicates in column A?
This comment was minimized by the moderator on the site
Hi Kristin,To combine cells in column M based on the duplicates in column A, try the VBA below.In the code,Â  O1 is the first cell to output the results; M is the column you will combine based on the duplicates in column A; A1 and A represent the first cell and the column where the duplicates locate; No and Combine color is the header of the columns after concatenating.Â You can change these variables as needed.<div data-tag="code">Sub ConcatenateCellsIfSameValues()

I just wanted to thank you. It wasn't exactly what I wanted but man did it help me figure out what to do.

I have a table where the person's name was in column A, dates in column B and the names of tools they use in the headers of columns C:G . In each column there is a "Y" if they used that tool on that date and blank if they did not. (FYI: the same person can be listed more than once and may have used the same tool more than once) On a separate (summary) page I wanted to list all tools each person used within a date period, only listing each tool they used once, in the same cell. On this page, the person's name was in column A, Types of tools used in column B and the helper columns were in column G:K. Here's what I got:
The first helper column (G2):
=IF(COUNTIFS(Table7[Person's Name],A2,Table7[Screw Driver],"Y",Table7[Date],">="&1/1/20,Table7[Date],"<="&3/31/20),"Screw Driver","")
In the last helper column (K2):
=IF(COUNTIFS(Table7[Person's Name],A2,Table7[Hammer],"Y",Table7[Date],">="&1/1/20,Table7[Date],"<="&3/31/20),IF(J2="","Hammer",J2&"/"&"Hammer"),J2)

In B2 I just entered =K2

Thanks again and I hope this helps someone. EZPD

Hi, first of all thanks for creating this resource. I have been trying to figure this out for a couple of hours and I'm stuck. I'm using your 'concatenate cells if same value' but my script is looking at column "D" instead of "A. I can't figure out how to get it to use a different column for the data besides the one right next to it. In my cases I want it to look at column "D" to see if the value is the same and if so, it will grab the data from column "H" and put that data from column "H' into a cell in column "J". How do I switch this to use column "H" for the data? Thx

Sub ConcatenateCellsIfSameValues()
Dim xCol As New Collection
Dim xSrc As Variant
Dim xRes() As Variant
Dim I As Long
Dim J As Long
Dim xRg As Range
xSrc = Range("D1", Cells(Rows.Count, "D").End(xlUp)).Resize(, 2)
Set xRg = Range("J1")
On Error Resume Next
For I = 2 To UBound(xSrc)
xCol.Add xSrc(I, 1), TypeName(xSrc(I, 1)) & CStr(xSrc(I, 1))
Next I
On Error GoTo 0
ReDim xRes(1 To xCol.Count + 1, 1 To 2)
xRes(1, 1) = "No"
xRes(1, 2) = "Products"
For I = 1 To xCol.Count
xRes(I + 1, 1) = xCol(I)
For J = 2 To UBound(xSrc)
If xSrc(J, 1) = xRes(I + 1, 1) Then
xRes(I + 1, 2) = xRes(I + 1, 2) & vbCrLf & xSrc(J, 2)
End If
Next J
xRes(I + 1, 2) = Mid(xRes(I + 1, 2), 2)
Next I
Set xRg = xRg.Resize(UBound(xRes, 1), UBound(xRes, 2))
xRg.NumberFormat = "@"
xRg = xRes
xRg.EntireColumn.AutoFit

Did you ever figure this out?

Hi,

looks like 2 of your formulas are wrong :

=IF(A2<>A3,CONCATENATE(A2,",""",C2,""""),""). You need to change "A2" to "D1". As you'll want to add the string to the previous cell.

same goes for this formula :

=IF(A2<>A1,B2,C1 & "," & B2) : Change C1 to D1.

kind regards

Harry

I use this VBA for lots of my spreadsheets and its great. But the spreadsheets have become very large 50k+ rows and it doesnt seem to be working any more. If I use it on 1000 rows it works fine but large sets of data it cant seem to cope with. No errors just no results. Any help would be appreciated.

Hi James,
I tested the code as you mentioned, but it still works well in my case even I set the rows to 1000+.

Using the VBA macro and getting great results, I have tried tweaking it slightly for my needs but cant get it to work so I hope you can help.

Which bit do I change to make it concat a specific column, not the one directly to the right of the xSrc = Range?

Thanks for your great work!

Or as a better option, if you had 3 columns instead of 2 and found duplicates in column A (like your example) can you concat column B into a cell and column C into a seperate cell? So if you had columns of Number, Colour, Age, could you concat colour and age into different columns upon finding duplicates in Number? Hope that makes sense!
