Concatenate cells if same value with formulas and filter


With the below formulas, you can concatenate corresponding cell contents if another column contains same value in Excel.

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.


Concatenate cells if same value with VBA code

Besides formula, in this section, we will show you how to use VBA code to concatenate cells if same value.

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 line Set xRg = Range("D1") means that the result will be placed in cell D1.

2. No and Combined Color in line xRes(1, 1) = "No" and xRes(1, 2) = "Combined Color" are the headers of concatenated columns. You can change them as you need.

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

    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!
