I have a analytic app where the user is presented with three interface tools. One of the tools is a Select File tool. I need to take that file tool they select and change it from an excel one column file with multiple lines to one line of text to then send to the update tool that will then feed the update value tool.
What could I do? This is the app. You see I need to connect to the update tool

The results of this is what I need to feed to the update tool
