can you store your excel file on OneDrive - Business –
“If you have OneDrive for Business and you sign into it with the same account you sign into Power BI with, this is by-far the most effective way to keep your work in Excel and your dataset, reports, and dashboards in Power BI in-sync. Because both Power BI and OneDrive are in the cloud, Power BI connects to your workbook file on OneDrive about every hour. If any changes are found, your dataset, reports, and dashboards are automatically updated in Power BI. Just like if you saved your workbook to a local drive, you can also use Publish to update your dataset and reports in Power BI immediately; otherwise Power BI will automatically synchronize, usually within an hour.”
