    From my investigation of the excel file, I found that one of the worksheets had invalid references and other issues. These prevented the workbook from resolving resulting values. This caused ADF to choke, preventing loading anything.

    After removing the offending worksheet, I was able to load data from the remaining sheets.

    The entire workbook must pass validation or else ADF cannot work with it. The error message was describing how it was unable to resolve references #REF!.

    Only '.xls' and '.xlsx' format is supported in reading excel file

    What is the name of your Excel file?

    What is the "IF" (prior activity) doing... I'm guessing that feeds in to your copy, does it apply to your Excel file and how?
