Hello Everyone … Wana ask if there is such integration between Unity and Microsoft Office ? and if so plz put some links or resources 
Depends what kind of integration you mean but in theory you can use any C# .net library for them, or maybe even OpenXML stuff.
Thank you…
You could always use office automation APIs through a native plugin. I don’t imagine it being pretty, though.
bump!
What’s the current status of Office app UI in Unity??
No status, you’ll have to implement it yourself.
