Hi,
First of all, may I know how you got the Office? Did you purchase and download it from the Internet, or was it from a deployment in your company?
If you downloaded it from Microsoft, I think it should be a click-to-run version. Before downloading it, you should be able to select the language, I suggest you logon the page where you downloaded Office, then select English, download it then re-install Office.
If you got the Office from your company, probably the wrong language is selected to install, check if other users have this problem and you may need to contact your administrator to select Engligh and re-install Office.
Some users may need a language pack or language interface pack in this scenario, learn more from this article below:
