I have attempted to restart both my ANKI and laptop, however, I just started getting this alert “Expecting value: line 1 column 1 (char 0)” when attempting to import a Quizlet set. I am about to try to uninstall the add-on and reinstall it. Just wanted to see if there was something else I needed to do? I tried looking through some of the other posts, but I am a little confused still.
From the documentation on Importing - Anki Manual (ankiweb.net), using File / Import from the menu, you can only import text files (CSV), packaged Anki decks created by the export feature, Mnemosyne 2.0 .db files, and SuperMemo .xml files.
