Power Platform Community Forum Thread Details

Hello, I'm a beginner in Power Apps and I'm trying to use Excel as a data source to build my power apps gallery. This is the issue I'm facing -
I'm trying to connect my Power App (Gallery) to an excel file uploaded to the teams channel. It should ideally let me select the excel file and build an app based on the table present in the excel file. Instead, it further shows another drop down and says "this file doesnt seem to have any tables". Can someone please help me out? Thanks!
