So you have an Excel 2007 file that's password protected and you don't know the password?
What is the source of this hex encoded password? What encoding was used when it came into existence? It's unlikely that Excel's password encoding is unknown to Excel, it's more likely that it's unknown to you and the program you're using to crack it.
Are you saying that "ê" is not one of the characters of the password? How can you know this if you don't know the password? You have to know something about the original password to be able to rule that out.
Are you 100% sure that this hex encoded password can unlock the file if it was written out in plain text (not hex encoded)?
Assuming that the original password was "qwerty", you can't unlock the file with its hex equivalent "717765727479" in extended ASCII. The password "qwerty" is "717765727479" regardless if you used ASCII or extended ASCII. Excel is expecting you to type in "qwerty", not "717765727479" or some other form of gibberish.
There is no magic, only a lot of hard work.
I think you're approaching the problem the wrong way. I haven't looked at this myself (yet) but here is some useful and commonly referenced bit of information:
