Can Microsoft Word translate my documents to and from different languages? Yes, and it’s easy. However, note that the Office 365 version requires the Office Intelligent services (included with subscription) and an Internet connection for the Translator feature to function.
Word asks if you want to “Turn On” this service the first time you use the Translate feature, which then remains “On” unless (or until) you disable the service from the Options menus. Additional features such as Editor, Smart Look Up, PowerPoint Designer, and more are included with these services.
Word 2013’s and Word 2016’s respective Translate features function essentially the same way, except the languages are located on your local system, and the menu design is slightly different.
