I was hoping to use the functionality of the Excel Writer to write to multiple sheets in one upload.
However, in the example on the KNIME website, it looks like you have to hardcode the individual sheet names…
Is there really no way to write multiple sheets whose names are defined by variables?
I think the option to write multiple sheets is potentially very useful but without being able to name sheets using variables i fear it’s nowhere near as beneficial as it could be.
There is an array variable you can use in the Flow variable tab of your excel writer node. You need to create the flow variable array with your sheet names first and connect it.

Hi Pete,
the idea is the same as for a normal variable. You can use a node (e.g cell splitter, column aggregator, string manipulation,…) to create the array first and then use table row to variable or a loop node to convert it into a variable.
