Excel Reader is not reading files individually

Hi, I just wanted to ask for some guidance on how to configure my KNIME workflow so that it reads excel files in one folder individually, processes them, and write each one into a separate file according to their commodity type (present as a column in each file). Right now, the end result is the data I want, but instead of writing each data into individual files according to their commodity code, it writes all the data (consolidated) into all output files renamed to their respective commodities. Here is my current workflow:

Here are my input files:

and here are my output files, which are all the same size because each file contains the identical, consolidated data:

Any help would be appreciated!
