Hi Amjad,
I have found another issue with 21.9.0, this time it (seems to) remove used styles
when calling “RemoveUnusedStyles”.
I have created a topic for this at (see the link below please)
but it does not allow me …...Save(myDir + "TestAsPoseExcel_NetCore_21_9_0_Bad.html", htmlSaveOptions);...Save(myDir + "TestAsPoseExcel_NetCore_21_9_0.xlsx", SaveFormat.Xlsx);...
