Creating Competitions Using PowerBI Reports

Reports must be added to a workspace.
The reports must be formatted as paginated reports. See: What are paginated reports in Power BI Premium?

Export your report from PowerBI as a CSV file
Create a new Competition in Spinify
Select 'PowerBI Data' as the goal metric
Select the workspace your report is in
Choose the PowerBI report you'd like to use for the competition (the results in this drop-down only include paginated reports, all other report types are filtered out)
Enter the column names for email and score from the CSV file exported in step 1
Continue to create the Competition as usual.
Note: If you're yet to create a competition, see: How to Create a Competition.
