You should be able to format those values as “normal” numbers in spreadsheet-programs (I’m using libreoffice, excel should work about the same).
I had little problem with finnish locale at my computer, becouse of decimal-separator, that is different in usa, so i had to import mooshi-csv:s in “american english”, which is easily selectable in libreoffice when opening those files. Not sure how excel would handle that. If you cant do any maths with your values, then this locale difference is probably reason for that.
