Looping through a list of Excel files

The idea of this workflow is to demonstrate how useful Loop Nodes in KNIME are.

You read a list of file(paths) and then iterate over them one by one, using the Chunk Loop Start Node.

Within the loop the path is converted into a variable and then fed into an Excel Reader.

This workflow goes along with my weekly newsletter aboud data analytics called "The Data Alchemist", click on the link below to find out more or subscribe for free.
