I am getting the below exception while uploading the csv file. Please provide your inputs
jxl.read.biff.BiffException: Unable to recognize OLE stream
Why are you using JExcelAPI (JXL) for reading CSV files? JXL is meant for Excel (.xls) files. Use a proper CSV library for reading CSV files; you can find several on our AccessingFileFormats FAQ page. And yes, I am aware that they are grouped under Excel there, but that's because Excel is usually the default application for CSV files. That doesn't make them proper Excel files.
