Yes you can. Easier to save the Excel workbook as a CSV file.
From there try doing something like this :
def var vInputField as char no-undo.
input from "drive:\directory\file.csv".
import delimiter ","
/* you can put your logic in here to do what ever
you need to do with vInput Field
NOTE: You can have as many input fields as you like...
I tend to make a vDummy field for columns
I don't need to use...
I also tend to use streams for flat file IO, but
easier for this example not to.
