“HeadingPairs” and "TitlesOfParts" tags are lost after conversion legacy PPT and XLS


Hi Aspose,

When I convert ppt to pptm, Aspose.Slides losts “HeadingPairs” and “TitlesOfParts” tags from the docProps\app.xml. I get same issue when I convert xls to xlsm using Aspose.Cells. But these tags are created correctly when I convert doc to docm using Aspose.Words.

Same conversion with MS PowerPoint and MS Excel doesn’t lose these tags. Issue can be reproduced on any ppt and xls files. I use Aspose.Slides v. 19.2 and Aspose.Cells v. 19.2.

Best regards,
Alex Shloma



Please share your sample files (PPT, XLS), the output PPTM and XLSM files and code snippet with us for our testing. We will reproduce the problem and provide our feedback after analysis.

For our reference share the working DOC and DOCM as well.
