Although it usually pays off to pay for professional translation, this can be nice for creating an initial draft, at least.
=GOOGLETRANSLATE(<source text>, “from language”, “to language”) where languages are encoded as the ISO two-letter language codes. You can also use “auto” as a language.
There is also a =DETECTLANGUAGE function that can be used to identify the language used in a range of cells.
