How to automate excel file (Lunchbox) workflow?

I want to automate the process of Lunchbox workflow.

As soon as i input the data as an excel file in a specific folder, i would like to get the output file in the same folder as a 3dmodel.

The problem is that everytime i drag and drop a new excel file into the directory,the process is not automatic and i have to re toggle the boolean button.

Is there any way to automate this process- once i put an excel file, i get the output in the folder without even touching the rhino (Runs in the background) ?
