I am trying to copy a worksheet from one workbook to another. For normal worksheets, my code
excelPackage.Workbook.Worksheets.Add("Target", origWS);
works fine. But when the same code is used for a worksheet that contains charts, I get an error
''type'' is a duplicate attribute Line 9, Col 150
This seems to be an issue in the XML structure of the excel file
Any help would be much appreciated.
