World languages in managed metadata store?

I'd like to publish a list of world languages to our enterprise managed metadata store, but rather then re-invent the wheel, I was hoping somebody out there had done the work and I could get a copy of the Excel spreadsheet to import. Anyone?

(Relatedly: Anyone know whether it's possible to import synonyms and preferred terms and the like? Looks like SharePoint Online just wants a list of parent/child terms in an Excel spreadsheet.)
