|My guess is that the dates aren't being recognized as dates by Excel.|
How did the dates get into the cells? Downloaded perhaps?
BTW, you should be aware that TRUE and "TRUE" are not the same thing.
TRUE is recognized as a logical TRUE (1) by Excel while "TRUE" (with the quotes) is recognized as the text string TRUE. The same holds for FALSE and "FALSE".
This may not make a difference depending on what you are doing with the "TRUE" and "FALSE" values, but I just wanted you to be aware that the quotes tell Excel that whatever is between them is Text, even if it looks like a number or a logical value.
