I am using your Aspose.Cells component (v 188.8.131.52) to convert an excel document to PDF. This works ok for some documents however I am getting an error for others. The error occurs on method Aspose.Cells.Workbook.Open(string). The error information is as follows:
Error Message: This is not a structured storage file.
Error Source: Aspose.Cells
Error Target Site: Void .ctor(System.IO.BinaryReader)
The corresponding excel file is a valid file (attached).
Please advise on timescales for a fix.
