Tasks backup could be improved

I just downloaded a csv backup of my tasks as I was getting worried about the risk of losing stuff, maybe without even realising (I now have EVERYTHING in there). However the csv file is a mess, I don't know how it would help me in the event I did lose tasks(?). There are """"" all over the place, for some tasks the data doesn't line up in the right column so I can't sort without doing a manual clean up, plus there is no header row and I can't even work out what some of the columns are (esp the true/false ones).... let alone whether tasks have been completed, whether the date refers to the date added or completed, etc etc.
