Uploading excel to sharepoint list via PowerApps

I am creating a powerapp which will allow the user to upload an excel data in to a sharepoint list. I tried doing it by following a video https://www.youtube.com/watch?v=45qSaxyS9Rg but it is giving me an error "No table was found with the name ‘Table1’." is there anyway to solve this or any other way to upload a an excel sheet to a sharepoint list via PowerApps.
