Batch Coupon Download

When I extract a batch of coupons to a csv, all the codes are neatly in a column except they all have an obsolete comma ( , ) after the code.  While I can remove this in the spreadsheet, i've never had this occur in any other codemaking software programmes so wondering if it is there for a reason or can be removed?

For eg - when copying a pasting codewords into a spreadsheet, I think they should look like:

1234
4578
4574
1277

etc

But they export as

1234,
4578,
4574,
1277,

?
thanks!

A comma is at the end of all CSV exports. 

I just downloaded coupons, opened it in google sheets and was able to copy all of the codes without a comma.
