Hi!
I had this problem previously... I didn't find THE solution, but I was able to go around the problem with copying my spreadsheet, pasting it in Word, CTRL+A, then under Format, Change case (sorry, my Word is in French, but this is under the Format menu, where you can choose all lowecase, all upper...etc.)
it's a pain in the ... but it is not that bad.
then I copy my text again and paste it in Excel. Since I had to do it many times, I personalized my toolbar to add this function [View, toolbar, perso.]
Good luck,
cixi
