data base small script

Data base small script. We have 8 csv files with hotels data in 8 languages. Need a small script in order to add a seperate column in existing csv files which will contains hotel's name + zip code of the hotel. Now we have seperate columns with hotels' name, and address + zip code. So need seperate extra column with hotel's name zip code as one unique id. The resons is to sychronise the all 8 languages of the hotels' csv with the existing hotels by using as unique id the hotel's name + zip code Need to get the script and instructions how to run it in case of future use
