Please notice, after an initial test, I am able to reproduce the issue as you mentioned using your sample file. When trying to save a range as HTML of file, it merges 2 columns and the result is different from the source. I have logged a ticket with an id “CELLSNET-50834” for your issue. We will look into it soon.
Once we have an update on it, we will let you know.
This is to inform you that the issue (logged earlier as “CELLSNET-50834”) has been resolved now. The fix will be included in the next release (Aspose.Cells for .NET v22.4) which is scheduled to be published before the end of this week (hopefully). You will also be notified when the next version is released.
