Excel changes case in formulas against my wishes

[tarpmaster]

I am using a 3rd party Excel Add-on that uses javascript to convert Excel spreadsheets to HTML. There are several formulas with this add-on that relies on formulas being case sensitive. For instance, I want the formula to say =wwsHideRows but then Excel automatically changes it to =wwshiderows. In that case, the formula does not work after conversion to HTML. I have tried fixing this problem with autocorrect, autocomplete and a variety of other "tools" options but I cannot get Excel to stop doing this. I think it has to do with remembering the formula the way I typed it once before. How do I clear Excel of that memory? Any other ideas?
