Kind of the inverse of this question.

I frequently download CSVs from outside sources as part of my programming work. I like to examine their data in Excel because, let's face it, Excel is an ideal tool for this sort of thing.

Except for one behavior: Excel attempts to outwit the data in the CSV, and therefore, if something looks like a number (like, say, many ISBN/EAN codes), Excel will treat it as such. And if this number is really big (like pretty much all ISBN/EAN codes), Excel will turn the number into scientific notation. Finally, if the number isn't particularly big, with most of these data formats, that indicates that Excel has decided that my number shouldn't have leading zeroes.

So ... Is there a way to open a CSV (via double-click if possible, but I'm willing to compromise here) in such a way that I can have Excel 2007 treat all the columns as text?
