Error - Unable to recognize OLE stream


When executing a custom plugin, I'm receiving the following error: Unable to recognize OLE stream


In the plugin jxl api's(Java Excel API) is used to read the Excel file. The JXL Api's does not support the Excel 2007+(.xlsx) it only supports the old BIFF (binary) ".xls" format and that is the reason it is throwing the error



  1. Parse only the .xls file using this custom plugin.

  2. Or try using the Apache POI Project to support both the formats. Please refer the below link for more information:
