How to disable Excel number autoformat

  1. cut and paste everything into note_pad
  2. delete what ever left in xl
  3. Select all needed cells, columns row to text format
  4. re-paste from note_pad
  5. if you need later you can change to date, time formats

Before you enter any values in the column/cells, change the cell format to Text.

Or, put this in the Workbook code module to force this formatting on all sheets, each time the workbook is opened.

Private Sub Workbook_Open()
Dim sh As Worksheet

For Each sh In Me.Sheets
    sh.Cells.NumberFormat = "@"
Next

End Sub
