Bulk edit multilingual item descriptions

I have multiple languages installed in store, I struggled editing descriptions in bulk, so I installed an app for that, worked great. The app was called quick bulk edit. The problem is it can only edit descriptions for the default language. What about the rest of the languages? I am struggling to find a solution for that. Theme related translations and collection names, checkout page, landing page etc, I am happy to edit that using exported language files or just shopify translate and manually adjust what is wrong. But looking at the exports and complicated html in product desc for 1000+ products, it is imposible to easily edit anything this way. Do you have any advice how to proceed with secondary languages?

Hi Hkckoo,
Shopify has a free app for translation. You can try it. Hopefully, it will help you.
