Fixing a date going to Excel

In the last few weeks I was looking for a solution to create a
csv file that would end up in a spreadsheet.

In one of my many searches, I found a very short article(paragraph)
that went into a method using a "script"??? that looked like this.
=date(mm dd yy) or something very similar.

This was placed in the field prior to the date so that Excel would convert the date correctly.

I think this is placed in the field or prior field.

Of course this is all tied back to the problems using cpytoimpf and date fields.

Anybody ever seen this ?
