Excel - Combine multiple columns into one column

Question

Hey everyone. I'm new to excel and VBA and I'm stuck at this problem.

I have multiple lists that are in separate columns in excel. What I need to do is combine these columns of data into one big column. I do not care if there are duplicate entries, however I want it to skip row 1 of each column.

ROW1| 1 2 3

ROW2| A D G

ROW3| B E H

ROW4| C F I

should combine into

A

B

C

D

E

F

G

H

I

The first row of each column needs to be skipped.

Answer 1

Not sure if this completely helps, but I had an issue where I needed a "smart" merge. I had two columns, A & B. I wanted to move B over only if A was blank. See below. It is based on a selection Range, which you could use to offset the first row, perhaps.

Private Sub MergeProjectNameColumns()
    Dim rngRowCount As Integer
    Dim i As Integer

    'Loop through column C and simply copy the text over to B if it is not blank
    rngRowCount = Range(dataRange).Rows.Count
    ActiveCell.Offset(0, 0).Select
    ActiveCell.Offset(0, 2).Select
    For i = 1 To rngRowCount
        If (Len(RTrim(ActiveCell.Value)) > 0) Then
            Dim currentValue As String
            currentValue = ActiveCell.Value
            ActiveCell.Offset(0, -1) = currentValue
        End If
        ActiveCell.Offset(1, 0).Select
    Next i

    'Now delete the unused column
    Columns("C").Select

    selection.Delete Shift:=xlToLeft
End Sub

Function Concat(myRange As Range, Optional myDelimiter As String) As String 
  Dim r As Range 
  Application.Volatile 
  For Each r In myRange 
    If Len(r.Text) Then 
      Concat = Concat & IIf(Concat <> "", myDelimiter, "") & r.Text 
    End If 
  Next 
End Function

Try this. Click anywhere in your range of data and then use this macro:

Sub CombineColumns()
Dim rng As Range
Dim iCol As Integer
Dim lastCell As Integer

Set rng = ActiveCell.CurrentRegion
lastCell = rng.Columns(1).Rows.Count + 1

For iCol = 2 To rng.Columns.Count
    Range(Cells(1, iCol), Cells(rng.Columns(iCol).Rows.Count, iCol)).Cut
    ActiveSheet.Paste Destination:=Cells(lastCell, 1)
    lastCell = lastCell + rng.Columns(iCol).Rows.Count
Next iCol
End Sub
