hello everyone, I am quite new to creating apps and would appreciate some help.
I am trying to create an app that will be shared within my and whose output will feed a dashboard every month.
the workflow will be fed from two excel files, both with different tabs and structures. But always with the same name for the tabs.
The idea is to create an interface where the app user selects the excel files and depending on the tab name it filters to run one workflow or another and the results are saved in the same excel output but in different tabs.
I have managed to do this when designing the workflows by adding each tab as a different input, but I am not able to make this selection done automatically from the file that the user selects.
I attach an image of the workflow so far.

thanks in advance.
