I think you'd be much better off reimporting the data into excel.

If you're importing a text file, make sure that the extension is .txt. Then
file|open your workbook and specify Text for that field.

But you could try a helper column with formulas like:

=IF(ISNUMBER(A1),TEXT(A1,"mm-dd-yy"),A1)

(But I'd start from scratch and re-import.)

Hello,

we have a large spreadsheet (Excel 2003) with bank codes that have been
automatically converted to date format. Any bank code in column G that could
also be a date, such as 03-07-78, will get converted to 03/07/78. Is there a
way to convert these 'dates' back to format for bank code (we do need date
format for other column)?

Thank you,
