Hi,

Please try below, change the date format as you want.
Sub ChangeDateFormat()

Application.ScreenUpdating = False
Set Ws = ActiveSheet

r = Ws.UsedRange.Rows.Count

Ws.Range("B:C").Insert
Ws.Range("A4:A" & r).TextToColumns Destination:=Ws.Range("A4"), DataType:=xlDelimited, _
  TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=True, Tab:=False, _
  Semicolon:=False, Comma:=False, Space:=True, Other:=False, FieldInfo _

Hmmm. The same can be done with a single line of code...

Range("A4:A" & Activesheet.UsedRange.Rows.Count).NumberFormat = "mm/dd/yy"

The reason being is that they are already real dates. Just format them how you want.
