Welcome to the most boring part of game development but everyone loves to see games adapted to their native language.

I have seen companies going nuts over this part of game development and I fully understand why. There's a package in Unity to do this. I am using Cocos creator 3.0. I am considering writing my own simple class. Here's my plan: I will convert every single word using Google Translate and prepare an Excel sheet or JSON, load these key values for different languages in a data structure and the user can convert this with the help of a Singleton class. I have a question though, is this good enough or there are problems which I am not aware of? Because I am getting the feeling that it's not that easy.
