Hi,
I just had a user report that a function that has worked for a long time suddenly does not any more. We are taking a pdf and saving as an Excel file. The website crashes with the error message below. It seems to me that the latest version of Aspose.Pdf (24.4.0) is dependent on a library that does not exist in our environment. This is an asp.net website using .NET framework 4.8. Note that when I reverted to Aspose.Pdf version 23.12.0, it worked fine. I will also put the code snippet below.
Please help and thanks.
// Load PDF document
Aspose.Pdf.Document doc = new Aspose.Pdf.Document(filePath);
// Instantiate ExcelSave Option object
Aspose.Pdf.ExcelSaveOptions excelsave = new Aspose.Pdf.ExcelSaveOptions { MinimizeTheNumberOfWorksheets = true, Format = ExcelFormat.XLSX };
// Save the output in XLS format (it really saves it as an xml file so we have to convert and can't save as xls format to web from pdf software)
MemoryStream ms = new MemoryStream();
doc.Save(ms, excelsave); // crashes on this line
