PPTX to PDF: Hidden data labels rendering after conversion (C# .NET)


I’m converting PPTX slides into PDF pages and the result is rendering data labels in the PDF page that weren’t visible in the PPTX slide.

Could you please investigate?
Thank you.


I have worked with the issue shared by you and request you to please first try using latest Aspose.Slides for .NET 20.2 on your end. In case the issue is still reproduced, please share the working sample code along with source file and generated PDF.

Hi there,

As mentioned previously, the issue we find is that the output PDF renders hidden data labels that are not showing in the input PPT.

Thank you for your help.
