What needs to be learned to develop this program?

Question

Text Processing Automation

I have a text file containing English words line by line. The task is for the program to copy the word, paste it into Google translate, copy the meaning (or 2 commonly used translations) and write the translation to the same line. And so it is with every word.
What do you need to know and be able to write such a program?
What is the best way to do this? (I think js is needed here)

Answer 1

In any server language (if JS, then node.js)
"pasted into Google translator, copied the value ..." translates as working with the Google Translate API

Answer 2

In any language there is a work with files.
