The expected output should be a file which contains updated ids (with new terms) and new ids, in case terms does not exist.

In other words, if an EN term of the second file exists in the first file it should be added under the same term. Otherwise, it should be added as new term.

Do you have any idea on how can I start?

Thanks in advance for your time and consideration.
