Hi Aspose team,
like in my ticket PowerQueries gone after Source replacement after changes in PowerQueries are done with Aspose.Cell they are disappearing which is killing document.
When change is done and new document is saved if I open file and go to Data => Show Queries they are not visible anymore.
Can you please check attached project?
Thx,
Oliver
