Aspose Slides breaks something in PowerPoint files with embedded chart and data.
I have a pptx file with an empty slide (PR26789_simple_1_slide.pptx).
Into this slide I copy a graph with embedded data (PR26789_original_with_embedded_data.pptx).
The data can be edited – see attached screen dump – EditGraph.
However, data cannot be edited any more after a simple Aspose Slides Open/Save operation (PR26789_refined_data_not_editable.pptx).
The very simple code for open/save .pptx file is included In AsposeSlidesOpenSaveTest.aspx
We have tested with Aspose Slides, v 18.4.0. (and older versions).
I really hope that You can help. In situations like this we need help to regain our customers/users faith in Aspose.
Thanks and kind regards
