The worst of it is that there are some very specific (and undocumented) edge cases where the translation won't be done properly.
It create very 'fun' to debug issues where a spreadsheet would work in a French Excel and not in an English one.
(For instance if you use the "Row-Column" cell reference, in English it is `R1C1` while in French `L1C1` - and it won't translate)
