I was unable to read the Excel file from my pentaho ETL server repository. I get this error:

unable to recognize OLE stream

What does that error mean?

See the solution in comments.

The file contained an XML page that was saved as an .xls file. Converting this file solved the issue.

On double clicking the Microsoft Excel Input, change the Spread Sheet Type(Engine) as Excel 2007 instead of Excel 97-2003 which will be the default selected one, now you can add your excel file and the fields will be generated.

  • This mybe usefull but still does not answer the question `What does that error mean?` please provide more details about the fix you are proposing – phoenixstudio Jan 18 '21 at 11:20
