Excel “External table is not in the expected format.”

Question

I\'m trying to read an Excel (xlsx) file using the code shown below. I get an \"External table is not in the expected format.\" error unless I have the file already open in

Answer 1

I was getting errors with third party and Oledb reading of a XLSX workbook. The issue appears to be a hidden worksheet that causes a error. Unhiding the worksheet enabled the workbook to import.
