vba to insert character in front of every string of numbers column 'A'

I need to an x to every every string of numbers in column A starting at A2

so if cell A2 = 012345678 I need to add an x so that it becomes x012345678

The number of rows will vary every day and I would like to use VBA please.

Thanks

this should do
 Public Sub x()
  Dim r As Range
  Dim c As Range
  
  Set r = Sheet1.Range("A2:A" & Sheet1.UsedRange.Rows.Count)
  For Each c In r.Cells
    If Not (c.Value2 Like "x*") Then
      c.Value2 = "x" & c.Value2
    End If
  Next
  
End Sub

Hi,

...and this code checks if the value is actually numeric, rather than not being prefixed with an "x":

Option Explicit
Public Sub Q_28375881()

  Dim objCell                                           As Range
  
  Worksheets("Q_28375881").Select
  
  For Each objCell In Range([A2], Cells(Cells.Rows.Count, 1).End(xlUp))
  
      If IsNumeric(objCell) Then
         objCell = "x" & objCell.Text
      End If ' If IsNumeric(objCell) Then
  
  Next objCell
  
  Set objCell = Nothing
  
End Sub

Open in new window


Please also see the attached workbook.

BFN,

fp.

PS. There will be a finite limit to the number of characters than the IsNumeric() function can handle.

If you could advise what the maximum number of characters will be in each of the cells in column [A] (row 2 onwards), then the code above may need to change to test the numeric value of each character instead.  (This could be achieved using Regular Expression syntax for speed).

Both great solutions. EE forces me to say one was 'Best Solution' but they are both equally as good. Thanks
