In Stylepicker, I selected CSV, next I used OpenOffice to open the file and after trial and error found this setting to be perfect. Including 2 screenshots.

(1) the setting to use for OpenOffice
(2) a view of the spreadsheet.
PS: the CSV is 2 Megs, saving in Excel 97 is also 2 Megs, however saving it in ODS format is only 1 Meg.

Enjoy
