Hi @Max_Cantelo
I don't think there is an easy way to make this work but you may be able to do some tedious workarounds.
My initial thought (and this has not by any means been tested) would be to build a workflow that could compare a previous Excel file to an updated one. If there was a change made to the file like a higher row count you could maybe use the message tool and run command to trigger the execution of a second workflow if the given conditions are met. If the first workflow was scheduled consistently then the second workflow could be triggered on the same schedule.
Sorry I wasn't able to help more. Good luck and keep us updated :)
