IssueWhen attempting to connect to an Excel file saved as a "Strict Open XML Spreadsheet" file type using the standard Excel connector, an unexpected error occurs. The following additional behaviors may also occur depending on your Tableau Desktop version:
Tableau Desktop 10.0-10.1
The error "Executing query" runs indefinitely but ultimately end in "Failed to Connect to database".
Tableau Desktop 10.2-10.5
The connection immediately fails with
"An error occurred while communicating with Excel Reader.
Unable to connect to the Excel file. It might be corrupt.
Try opening the file in Excel, saving it under a new name, and then connecting from Tableau again."
