I am opening a csv file in excel with many columns in the US date
format (mm-dd-yyyy). I need these all to be in the UK format
(dd-mm-yyyy). When I run text to columns on each column individually I
can choose the column data format MDY and it will reformat the dates
correctly. However when I recorded a macro to do this it doesn't work.

Does anyone have any idea why this works when you do it manually but
not via a macro.

Columns("A:A").Select
Selection.TextToColumns Destination:=Range("A1"),
DataType:=xlDelimited, _
FieldInfo:=Array(1, 3)

and repeated for each column

Thanks,
Andy
