I need to process a file in which there is a string column, for each of the values of that column I must create a directory and a file with the rows to which that value corresponds, for example for the category “CO Investment” one should get the following : host/CO Investment / CO Investment.xlsx. Inspired by the flow ( Create multiple folders – KNIME Hub ) contributed by @Kathrin I created the following flow: Folder file creation.knwf (2.4 MB) I have two issues: 1.- Why the file corresponding to the first value of the Group Loop node is being written? 2.- The workflow looks over complicated, is there a simpler way to do it?

Creating Folders and writing files

@iperez here I tried to illustrate how the path generation does work.

Also most writers allow the option to create missing folders, although I like the option to only create new folders deliberately.
