Hi @adaptagis

but in your workflow you are using the Table Writer, which will always write the KNIME Table format, independently of any name created with the Create File Name Node.
If you want to write an Excel File you need to use the Excel Writer node in the loop.
Or for CSV the CSV Writer.

Cheers, Iris

Hallo Iris

I see… so to run the create file name node properly, you not only have to choose the deisred format in the configs but attach the adequate file writer to it… makes sense… ;-p
