...Why? There's literally no reason for that, even if it were possible/feasible. Functionally, the Office suite would be a nightmare to handle with a controller, and even if you were to hook up a keyboard and mouse like
@Dirty Hipsters suggests, what they hell would you need the suite for on a gaming console? Outside of "I'm on a desert island, and all I have is my Xbox, Wi-Fi, and the need to tidy up my resume or do my taxes," there'd be absolutely no situation in which the convenience of Office on the Xbox would outweigh the already benefit of having it on your PC/laptop
where it belongs.
