In summer 2018 there is something interesting in Office 365 updates. 

The Power Pivot add-in, which was until now included in more expensive Excel versions only, is now available in nearly all commonly used versions – even in cheap individual and household versions.

So, from now, you can enjoy working with data model with your family 🙂

 

The add-in can be activated by File / Options / COM add-ins. There Power Pivot appears in a new ribbon.
