It’s easy to fill all cells with same content in a column with the AutoFill feature. But, how to add same prefix or suffix to all cells in a column? Comparing to type the prefix or suffix to each cell separately, Kutools for Excel’s Add Text utility provides an easy workaround to get it done with several clicks only.

You can also deal with this problem with the following VBA code:

1. Select the range that you want to insert the prefix or suffix.

2. Click Developer > Visual Basic, and a new Microsoft Visual Basic for applications window will display, click Insert > Module, and then input the following code:

Sub AddTextOnLeft()
'Updateby20131128
Dim Rng As Range
Dim WorkRng As Range
Dim addStr As String
On Error Resume Next
xTitleId = "KutoolsforExcel"
Set WorkRng = Application.Selection
Set WorkRng = Application.InputBox("Range", xTitleId, WorkRng.Address, Type:=8)
addStr = Application.InputBox("Add text", xTitleId, "", Type:=2)
For Each Rng In WorkRng
    Rng.Value = addStr & Rng.Value
Next
End Sub

Sub AddTextOnRight()
'Updateby20131128
Dim Rng As Range
Dim WorkRng As Range
Dim addStr As String
On Error Resume Next
xTitleId = "KutoolsforExcel"
Set WorkRng = Application.Selection
Set WorkRng = Application.InputBox("Range", xTitleId, WorkRng.Address, Type:=8)
addStr = Application.InputBox("Add text", xTitleId, "", Type:=2)
For Each Rng In WorkRng
    Rng.Value = Rng.Value & addStr
Next
End Sub

3. Then click Run button or press the F5 key to run the VBA.
