I've got a list of items that i upload to a website which include a title / product id etc etc, i upload this file to a website which then allows me to download a .csv file or all the items that are currently active on the site with a seperate id tracking number. I'm strugling to find some code that will read the downloaded csv, scan that file for the title / product id from the original spreadshet then off the same row from the downloaded csv copy the id tracking number, then paste it on the corresponding line in my open spreadsheet.

I'd like to click a button, select which csv file i'd like to use, the script to then copy the correct number into my existing spreadsheet. Is this possible?
