Error uploading Excel file (.xlsx)

Question

Trying to upload an Excel file I got following error:

"Error: Dati di input (14): Error opening connect string: Microsoft JET Database Engine: La tabella esterna non è nel formato previsto.\3274 = -328602519 - Errore non specificato."

Has someone idea of the cause ?

Thanks in advance for the support.

Hi @boschi!
I'm here to help - would you be able to provide a bit more information? When you say you're trying to upload an excel file, can you share a screenshot of the Input Tool & configuration you're using as well as, if possible, a description of the data table itself? 
From the error it looks like the format of the table is causing the issue!
