With the Power BI add-in for PowerPoint you can embed your reports within a presentation. When embedded, the report is interactive- so that means during the presentation you’ll be able to click into your report to drill up/down and apply filters.

Begin by opening your PowerPoint presentation. Go to Insert > Get Add-Ins and look for Power BI. Add the one published by Microsoft.
The Power BI add-in will then be available in the ribbon. All you need to do now is get the URL of the report you want to embed. Note: this feature only works with reports, you cannot embed dashboards.
Go to https://app.powerbi.com/ and open the report. Copy the URL, then paste it in PowerPoint. You can also resize and change the position of the report on your presentation.
In a moment, you’ll see your report embedded, and it’s ready to use.
