PFA zip with cs file.
Conversion of pptx and xml is not working. Plz check the below methods:

- private void button19_Click(object sender, EventArgs e)
- private void button20_Click(object sender, EventArgs e)

@subramanyam.gvsrb

Thank you for sharing the information. However, I am still unable to find 17.xml that you are trying load and getting exception with.

subramanyam.gvsrb · March 26, 2021, 1:33pm

In place of that file, you can have any test xml file… this code block is giving an issue for each test file.

mudassir.fayyaz · March 26, 2021, 3:13pm

@subramanyam.gvsrb

I request you to please share the source XML that is reproducing the issue so that we may understand the root cause of the issue. This issue seems to be related to a particular XML.

Thanks for the update.

Can you plz update on ppt conversion issue?

Hello @subramanyam.gvsrb.
The attached XML file is valid, please use it.

subramanyam.gvsrb · April 1, 2021, 10:12pm

Plz update on PPTX…

alexanderefremov1 · April 2, 2021, 4:29am

@subramanyam.gvsrb
PPTX is not a format that supported by Aspose.Tasks, because PPTX is a presentation, not a project management file. If you want to work with PPTX you may use Aspose.Slides instead.

subramanyam.gvsrb · April 2, 2021, 4:57am

I have used the slides, not able to open output file.
