I've got a macro-enabled workbook that works just fine in Office365's version of Excel but earlier versions are breaking all over the place. If anyone could provide direction, I would appreciate it! The current issue is with this bit below:
Range("1:1").Select
Selection.Find(What:="eventdate", After:=ActiveCell, LookIn:=xlFormulas2, LookAt _
:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
False, SearchFormat:=False).Select
Range(Selection.Offset(1, 0), Selection.Offset(1048570, 0).End(xlUp)).Select
Set rng = Selection
For Each eventdateCell In rng
eventdateCell.NumberFormat = "@"
eventdateCell.Value = WorksheetFunction.Text(eventdateCell.Value, "yyyy-mm-dd")
Next eventdateCell
