Sparkle line disappears after PDF export

Good day

Please have a look at attached files. One file is the excel file before it gets processed and exported to PDF the second one is after. Also I attached the PDF file.

For some reason the Sparkle 's gets removed when I do the export to PDF


Thanks for the sample files.

After an initial test, I am able to reproduce the following two issues as you described:
  • CELLSNET-45280 - Sparklines disappear after re-saving the file
  • CELLSNET-45281 - Sparklines disappear after rendering to PDF

I used the following sample with your template XLSB file:
Sample code:

Workbook workbook = new Workbook(strFilePath);

Our product team will evaluate your issues soon. Once we have an update on any of the issues, we will let you know here.

Thank you.


We noted it we change it to a normal .xlsx file it works fine


Yes, you are right but in that case (i.e., if your template XLSB file is changed to XLSX file format), vba codes/ macros might be lost. If you don’t want to use/retain macros/ vba codes in the template file(s), then you can live with it.

And, please spare us little time as we are investigating your issues (logged as “CELLSNET-45280” and “CELLSNET-45281”).

Once we figure them out or we have some other update on any of the issues, we will let you know here.

Thank you.


It is to update you that currently Aspose.Cells does not support reading and writing Sparklines in XLSB file format. We hope we can support it before the end of this month or in the start of next month.
