Why is it so hard to just translate a book and put it into a downloadable file?

I'm trying to translate an accounting book I downloaded and make it a download able file with AI

I've tried chatgpt, Claude. Even deepseek

I've been at it for like an hour with deepseek because neither Claude or GPT can make a file from it. The first time with deepseek it gave me a download link that doesn't work

And the next tries, it just generates the translation without giving me a file to download. Each time I tell it "give me a file I can download" it just regenerates the translated version no matter how it word it. Instesd of just giving me the fucking file it just generates the entire thing over again

I thought deepseek was suppose to be this powerfull AI and it can't do this?

I am so frustrated right now. I can't just copy paste it because the formatting is not the same. I can't just paste it onto word because the questions and formatting and columns won't be there
