Hello,

I made the mistake of using Excel 2007/2010 in two different languages on two different computers. Almost all formulas have a different name (http://wwwhome.ewi.utwente.nl/~tries...cel/excel.html) but I learnt everything I know with the English one so it's quite a pain.

However, when I open one file made with one version with the other version, all formulas are correctly translated automatically, which makes me think that there must be a way to change my non-English version to an English one? I can go to the "Excel Options", but "Language" only allows me to define the language for display and spelling check.

Thank you very much in advance for your help!
