Hello All

I was looking to create a macro that would combine all column values in one single column using a delimiter (comma)
I have variable column numbers per row

[TABLE="class: grid, width: 100, align: left"]
<tbody>[TR]
[TD]A[/TD]
[TD]D[/TD]
[TD][/TD]
[/TR]
[TR]
[TD]B[/TD]
[TD][/TD]
[TD][/TD]
[/TR]
[TR]
[TD]C[/TD]
[TD]E[/TD]
[TD]F[/TD]
[/TR]
</tbody>[/TABLE]






Result:

[TABLE="class: grid, width: 100, align: left"]
<tbody>[TR]
[TD]A, D[/TD]
[/TR]
[TR]
[TD]B[/TD]
[/TR]
[TR]
[TD]C, E, F[/TD]
[/TR]
</tbody>[/TABLE]






Please help
Apologies if this has already been asked before

Thanks in advance
P

Welcome to the board. The following code assumes your data starts in cell A1 and that the first row defines the last used column and outputs the results next to the last column:
Code: 
Sub Macro1()


    Dim arr()   As Variant
    Dim x       As Long
    Dim y       As Long
    
    x = Cells(Rows.Count, 1).End(xlUp).row
    y = Cells.find(what:="*", after:=Cells(1, 1), lookat:=xlPart, LookIn:=xlFormulas, searchorder:=xlByColumns, searchdirection:=xlPrevious).Column + 1
   
    arr = Cells(1, 1).Resize(x, y).Value
        
    For x = LBound(arr, 1) To UBound(arr, 1)
        For y = UBound(arr, 2) - 1 To LBound(arr, 2) Step -1
            If LenB(arr(x, y)) > 0 Then arr(x, UBound(arr, 2)) = arr(x, y) & ", " & arr(x, UBound(arr, 2))
        Next y
        arr(x, UBound(arr, 2)) = Left$(arr(x, UBound(arr, 2)), Len(arr(x, UBound(arr, 2))) - 2)
    Next x
    
    Cells(1, 1).Resize(UBound(arr, 1), UBound(arr, 2)).Value = arr
    Erase arr
    
End Sub

Hello JackDanIce

Thank you for your prompt reply

The macro you've written does solve my issue :)

However, my columns start from B
and I was wondering if it is possible to get the results in column A
as I will be processing it further

Thanks
P

Try:
Code: 
Sub Macro2()

    Dim arr()   As Variant
    Dim x       As Long
    Dim y       As Long
    
    x = Cells(Rows.Count, 2).End(xlUp).row
    y = Cells.find(what:="*", after:=Cells(1, 1), lookat:=xlPart, LookIn:=xlFormulas, searchorder:=xlByColumns, searchdirection:=xlPrevious).Column + 1

    For x = LBound(arr, 1) To UBound(arr, 1)
        For y = UBound(arr, 2) To LBound(arr, 2) + 1 Step -1

    Cells(1, 1).Resize(UBound(arr, 1), UBound(arr, 2)).Value = arr
    Erase arr
    
End Sub

pratnimk,

Welcome to the MrExcel forum.

Here is another macro solution for you to consider, that uses two arrays in memory, and, will adjust to the number of raw data rows, and, columns.

Sample raw data in the active worksheet:


Excel 2007
ABCDE
1AD
2B
3CEF
4
Sheet1


And, after the macro:


Excel 2007
ABCDE
1A, DAD
2BB
3C, E, FCEF
4
Sheet1


Please TEST this FIRST in a COPY of your workbook (always make a backup copy before trying new code, you never know what you might lose).

1. Copy the below code
2. Open your NEW workbook
3. Press the keys ALT + F11 to open the Visual Basic Editor
4. Press the keys ALT + I to activate the Insert menu
5. Press M to insert a Standard Module
6. Where the cursor is flashing, paste the code
7. Press the keys ALT + Q to exit the Editor, and return to Excel
8. To run the macro from Excel press ALT + F8 to display the Run Macro Dialog. Double Click the macro's name to Run it.

Code: 
Sub MergeData()
' hiker95, 02/08/2017, ME990036
Dim a As Variant, i As Long, c As Long
Dim o As Variant, lr As Long, lc As Long
Application.ScreenUpdating = False
With ActiveSheet
  lr = .Cells.Find("*", , xlValues, xlWhole, xlByRows, xlPrevious, False).Row
  lc = .Cells.Find("*", , xlValues, xlWhole, xlByColumns, xlPrevious, False).Column
  a = .Range(.Cells(1, 2), .Cells(lr, lc))
  ReDim o(1 To UBound(a, 1), 1 To 1)
  For i = LBound(a, 1) To UBound(a, 1)
    o(i, 1) = a(i, 1)
    For c = LBound(a, 2) + 1 To UBound(a, 2)
      If Not a(i, c) = vbEmpty Then
        o(i, 1) = o(i, 1) & ", " & a(i, c)
      End If
    Next c
  Next i
  .Cells(1, 1).Resize(UBound(o, 1), UBound(o, 2)) = o
  .Columns(1).AutoFit
End With
Application.ScreenUpdating = True
End Sub

Then run the MergeData macro.
