To improve my current product, I was looking for a command line tool to translate my data set. I did a quick benchmark this weekend.
The best tool I found is https://github.com/soimort/translate-shell
It allows to translate some words, expressions, or documents using Google Translate, Bing Translator, Yandex, etc, directly from your terminal!
You can install it with docker or as a cli tool. I used it for French and Spanish translations of my English data set. It saved me a ton of time, I had 5000 expressions to translate, the translations are pretty decent, good enough for my use.
You can see the result on my current product, the fastest emoji search engine ever, now supporting new languages 🇬🇧+🇫🇷+🇪🇸= 🔍⚡
