I'm very new to PowerApps and have some task of making the app which will involve incremental data load. Currently we have chosen Excel sheets as the data source. So the actual task was make the data to be read from one Excel file and written to another Excel file somehow keeping track of new records since the last load. I was searching online but didn't find any such scenario. So there is a question: is such scenario possible/reasonable at all using Excels? And if not what would you recommend as data management system for such purpose working with PowerApps platform? Many thanks.
