Newbie - Open CSV, copy column, paste to website and copy results

Hi! Very new, have been playing around for a few hours.

I have a .csv with 34,000 number plates. I want to go to

Read the 1st line, copy, paste into website and click through to produce a result. I then want to copy one part of the result into the same csv file.

e.g I am trying to store the Emissions of the vehicles.

I have done
CSVread plates2.csv
open $(!col1) - but it doesn’t seem to copy line 1?

Use Y88CEM as a test plate.

You must use Type to paste the value from a csv not open
