This task seems easy, but is turning out to be more complex than I expected. I have a excel spreadsheet that I have imported into a custom list. In order to import the excel spreadsheet by using "Import Excel Spreadsheet" app. My objective is to import a new excel spreadsheet but overwrite the existing custom list. Is there a way to do this without having to delete every item in the custom list and trying to import a new list (if possible)?
Let me know if you need more information. Thanks!
