Data Export to CSV - wrong formats for price

Hi there,

when exporting products into CV-file in the column AT (=product_sort_price) some prices are shown in the right format (Excel. "Standard").
Others are given in a date-format, e.g. "Sep99"; although in the backend the correct price "9.99" (EUR) was entered.

Please see CSV-file in attachment, column AT.

Thanks.

Rolf

P.S.: Additional question - what format must CSV-file be stord CSV /S-DOS, or CSV-separators?
