Hello T-C
I think there is no need to create script variables if you would like to use the values from excel. You can use the file reading commands (python) to read values from excel and reference them in your script. Under "Insert Code Snippet" option (located next to the record button), you can find one example of reading csv file. See below snapshot. Similarly, you can read excel file and its data. You can get several examples on google regarding excel import using python.
