Daily Auto-Updating Power BI Dashboard

I keep all of my raw data in a set of Excel spreadsheets and I need a Power BI dashboard that can pull from those files, refresh itself automatically every day, and present the numbers that matter most to me—customer-demographic insights and operational-efficiency snapshots.

The work involves building the .pbix report, configuring a reliable scheduled refresh (Gateway or cloud-based, whichever fits best), and making sure the visuals clearly surface trends and outliers without any manual intervention on my side. Once published, I should be able to open the dashboard each morning and see up-to-date figures.

Please deliver the finished Power BI file along with any connection or gateway settings I need to keep the daily refresh running smoothly, plus a short hand-off note so I know how to swap in new Excel files or adjust refresh times later.
