The file itself may be using the magical format m/d/yy (which is interpreted in different ways depending on the locale).

If you want to reformat the dates, pass the option cellDates: true to generate date objects, delete the w fields for date cells and replace them with the format of your choice.

At some point we will offer a more general solution
