Hello Domond, Patrick,
Thank you for reaching out on the Microsoft Q&A forum.
Please go to the Create tab and select Blank canvas app, then choose the Tablet format. Once the app opens in Power Apps Studio, navigate to the Data section and click on Connect to data. From there, select OneDrive for Business as your data source. Locate and select the CoffeeMachineData.xlsx file that you've saved to your OneDrive.
After selecting the file, choose the CoffeeMachines table and connect it to your gallery. This will allow your gallery to display the data from the Excel file. Make sure that the Excel file is stored in your OneDrive for Business and that the data is formatted as a proper Excel table.
Kindly refer to the below screenshots for guidance.
