First, we need to get a code for the report, open the report then click File > Embed (You can select ‘Publish to web’ - this means you don’t need to login to view the report, however anyone in the world could access the report)
Once you’ve selected embed, you need to copy the iframe code
If you copy the code below into notepad inserting the iframe code then saving it as a .html (for example report.html)
One thing worth changing on the iframe code Power BI generates is changing the frame size.
This is allow Power BI to use the full web browser real estate. You can ofcourse use F11 to make most web browsers go full screen. Great for displaying Power BI on the big screen!
