Re: [DataFormat.Error] External table is not in the expected format.

Ankit,

Thanks - using the SharePoint Folder approach has the same result.

I can see the folder, and see the .xls files. 

However, when I click the Content column to combine binaries, I get the same problem.

(Excel.Workbook(#Combined Binaries) is auto-generated upon clicking the double down arrows in the Content column shown above).
