Limited output Xbrowse to exel or csv

Hello, I need to export data into a exel or csv file. (for later import into Prestashop shopsystem) One field is a memo field (dbt or fpt), that can be large (200-600 chars) I have a point that I can export to exel from Xbrowse, but I see that exel is limited to 255 char in a colom ! I can us COPY TO update.csv DELIMITED, but also this will only give approx 255 char ? How can I overcome this limit ? I need to have 1 large field, since the import module from Presta alows 1 field for each imported field. Marc
