Hi All,
there is Exception when I am trying load excel.
the error message is "Unable to cast object of type 'Spire.Xls.Core.Spreadsheet.Charts.XlsChart' to type 'Spire.Xls.Worksheet'."
below is my code
Workbook book = new Workbook();
book.LoadFromFile("sample.xls", false);
By the way, i use this spire soft which is 'spire.office-fe_2.15'.
if change type of the excel from xls to xlsx, so it's success when to load.
How to fix with loading xls file?
I look forward to your reply.
thanks a lot.

Hello Jane,
Thanks for your reply.
I think i need to fix it via other way.
Maybe first change excel type from xls to xlsx, and then i use spire to load it.
