Simple CSV File / Worksheet Generator

Hi there, After a quote to do the following work: CSV file creator based on xlsx data. XLSX worksheet creator based on existing worksheet. The following conditions must be met: Built using anacondas 3.6 modules Must be easy to extend/update if need be This script that needs to do the following: Read from a filepath on a windows directory an xlsx file Enumerate through large amounts of values quickly from multiple named/headed columns and write them to a new worksheet under headed/named columns in the same xlsx file. I would also like some seperate logic to do the same thing but write it out to a new CSV file under named columns. Script needs to be able to enumerate through the values of 10-15 columns minimum. Its a simple enough task to do in python but i just dont have the time to do it [login to view URL] use commenting in the script. Thanks!
