Recently, I have studied Spanish but, I am so tired of making word cards by typing each time. How can I automate this tedious work?
Read these guidelines and ask a good question. In particular, what is this tedious task that you want to automate? Typing? Well, hire a typist or use text-to-speech software. LibreOffice can’t type for you.
First hit (for me) in this search leads to Add-on for converting bulletpoint lists into Anki cards, maybe that helps.
