i am trying to add an excel file and create feature layer using the add item button on enterprise portal. the excel file is attached below. whenever i try to add it, the field names and field types are not read correctly and displays field names as "field1","field2" and so on. if i add the same file in arcgispro, using add data button, then it displays correctly. However when i change my columns to strings then it works fine in portal. is there a way i can make it work without changing my field names into string?
