If it's just one cell tryorCode:Range("A8").Value = Split(Range("A8").Value, "of")(1)
to convert to a dateCode:Range("A8").Value = CDate(Split(Range("A8").Value, "of")(1))
Sorry for this being irrelevant to OP question but ....
Does Split put items into an array of some sort? and is the (1) calling the second index of that array which in this case would be the date?
