Save Excel to PDF


I have written a very simple console application to export an excel file to PDF, but application is taking for ever to export to pdf. It has already run for about and hour still no success.
Can you please help?

The excel file is 5.14 MB and has 115996 rows.

Stopwatch sw = new Stopwatch();
Workbook book = new Workbook(“xyz.xlsx”);
book.Save(Path.ChangeExtension(book.FileName, “pdf”), SaveFormat.Pdf);

Hi Ricky,

Thanks for your posting and using Aspose.Cells.

Please download and try the latest version: Aspose.Cells for .NET 8.2.1 and see if it resolves your issue.

If your issue still occurs, then please provide us your source Excel file which you are converting to PDF. We will try to convert your Excel file into PDF at our end and in case, it is a bug, we will log it in our database for a fix.

Thanks for the reply.
I used the latest version 8.2.1 but same result. The application ran for 3 odd hours before it generated the PDF.
Attaching the excel that I used.

HI Ricky,

Thank you for providing the sample spreadsheet.

We are able to observe the performance lag while converting your sample spreadsheet to PDF format while using the code snippet as provided below.


LoadOptions options = new LoadOptions();
options.MemorySetting = MemorySetting.MemoryPreference;
Workbook workbook = new Workbook(myDir + “xyz.xlsx”, options);
workbook.Save(myDir + “output.pdf”, SaveFormat.Pdf);
