I have a similar question to this one:
Merge the contents of 2 cells into another 3rd cell using VBA in Excel
But I want to combine a range of cells within a
Try the following macro, not very elegant in that it doesn't do any error checking etc but works. Assign the macro to a button, click in a cell, click the macro button, highlight the desired (source) range to merge using your mouse (will autofill in range in the input box in the dialogue box), click ok, highlight the destination cell (will autofill the input box in the next dialogue box) click ok, all cells will be merged with a single space character into the destination cell, which can be in the original source range). Up to you to delete the superfluous cells manually. Workks with both rows and columns but not blocks.
Sub JoinCells()
Set xJoinRange = Application.InputBox(prompt:="Highlight source cells to merge", Type:=8)
xSource = 0
xSource = xJoinRange.Rows.Count
xType = "rows"
If xSource = 1 Then
xSource = xJoinRange.Columns.Count
xType = "columns"
End If
Set xDestination = Application.InputBox(prompt:="Highlight destination cell", Type:=8)
If xType = "rows" Then
temp = xJoinRange.Rows(1).Value
For i = 2 To xSource
temp = temp & " " & xJoinRange.Rows(i).Value
Next i
Else
temp = xJoinRange.Columns(1).Value
For i = 2 To xSource
temp = temp & " " & xJoinRange.Columns(i).Value
Next i
End If
xDestination.Value = temp
End Sub
