How to read a csv files and get specific data


Plz help on below… which activity to use and steps?
I have a csv file having only Reference_ID column e.g “1234-REF” from a specific folder D:\project\temp\reference.csv

I need to loop thru each of these rows (apprx. 500 rows of reference_id data) from the csv, input the reference_ID in the application form and click on enter.
When data is available in the application form, need to read a specific fields(reference_name, quantity) in that form and write to the csv.

reference_id | reference_name| quantity

Read CSV activity is what you need to start with.

do u hv an examples / sample pls?
