I have been trying for some time to import an Excel file, perform a few minor functions and then export, while maintaining the original cell formatting (alignment, merge, bold, etc etc)
I have had little to no success with the number of methods I have tried.
These was some success with a virtualgrid, but any format changes (alignment, merge etc) would be immediately overwritten with the original formatting.
I have attached one of your samples "Cell Customization Demo" with a save added.
On opening the saved file, you will see the formatting has been mangled.
The documentation at Syncfusion is nothing short of terrible.
