Office documents not opening in MS Ofice

Hello

I have a number of office documents on my iMac.

Until recently when opening from Finder they would always open in word, excel, etc.

Now they are all defaulting to open in iWork apps and not Office.

Any idea what I've done and how to het back to the way things were?

Thanks, Nick

Right click an Office document > Get Info > Open With: > change to the appropriate program (if you're doing this for a document, change to word and so on) > Change All...

thank you
