Embedded chart data cannot be edited after saving with Aspose

Embedded chart data in a PPTX file cannot be edited after the file is saved using Aspose. When a chart is embedded in a PPTX file, you can right-click on the chart and edit the data in an Excel-like spreadsheet. After the file is saved by Aspose, the data can no longer be edited and appears to be lost although the chart is still displayed.

I am using .NET 4.6.1 with Aspose Slides in a 32-bit application. The file was saved using my client’s application which also writes data to the custom properties. I will work on getting a sample project for you.


I have observed your comments. Before sharing sample project i request you to please try to use Aspose.Slides latest version 17.7 on your end. If there is still an issue than please share requested information.

I will try using the latest version.

It looks like the latest version does resolve this issue. Thank you.


You are welcome.

Dear ASPOSE Support ,

What is the status of this issue? Can we raise the urgency since it has been open for 3 months?
