Manipulate Excel worksheet columns from Access

I am importing data from an Excel workbook into an Access table. A straight import works fine. Because of new requirements I now need to swap the worksheet columns around prior to import. i.e. column E needs to be in column A, A needs to be in H, B needs to be in F etc., etc. before the import can take place.(I have to leave the Access import routine as standard.) I am trying to grab a column at a time and write it to a new worksheet in its required column position. I have tried different techniques that I downloaded from various forums but they don't work. Is there actually a way of doing this without having to process a cell at a time ? (It has to done from within the Access form/code without the user being aware of the processing). I would be very grateful for any advice. Thanks.
