The problem is:
i create this script to send files attached on a e-mail. The e-mail list is xlsx where i have the colunm 0 with the name and colunm is the e-mail to send than i see the name of the file (is the same value of colunm 0) and send the e-mail. The problem is if i need to change the xlsx i'll have to convert again but this script will run on the user pc.
