I work heavily between KNIME and Excel and I find this node to be infinitely easier if you are proficient on the Excel side.
The Continental nodes are fine if you just want a few simple formatting rules applied to clean up a table, but if you really want to dial in a nice presentation it will cost you hours. I can do the same thing with the write to a template approach in a few minutes as well as include conditional formatting, user interaction settings, graphs, etc. You can also write around existing formulas (using blank cells on the KNIME side) to update data only where necessary keeping interactivity in tact.
