@wojciechpietrus I have updated this example with the new nodes and built in some additional features. The elements might be good to adapt.
There are three sub-folders with CSV files. The folders will be read in the first step and then the individual CSV files.
Per sub-folder there will then be an Excel File that would contain the CSV files as sheets. in the first iteration an existing Excel file would be overwritten and then the sheets would get appended. That also might serve as an example for a CASE SWITCH.
