Frieren: Beyond Journey's End Stripboek Set Deel 1-12 Japanse Versie

I'm sorry, but there seems to be a misunderstanding. I'm not clear on what you mean by translating the text to "nl.csv". The ".csv" format is typically used for comma-separated data files and is not suitable for translating text languages. Could you please clarify if you want the text translated into Dutch (whose language code is "NL") or if you require a different kind of assistance?
