brain-brew VS anki-uk-geography

I was able to use Brain Brew https://github.com/ohare93/brain-brew/ to import my CSV (eventually). You'll need some programming knowledge (I'm new to Python but I got it working). Basic steps for me was 1) Create a deck in Anki with 1 record; 2) export it in JSON (after installing CrowdAnki); 3) use Brain Brew to convert the JSON to files in a src directory - using the starter repo was helpful https://github.com/ohare93/brain-brew-starter; 4) include the CSV file in the project; 5) use Brain Brew to convert the src files into a deck that can be uploaded (a "build"); 6) use CrowdAnki to import the newly generated build.

Have you had a look at Brain Brew? It's the tool we use to manage the Ultimate Geography deck. First, you'd have to export your other deck with the CrowdAnki addon, then write a Brain Brew recipe to parse the CrowdAnki JSON export and spit out the data and note type to CSV/YAML. Once you have that, you'd have to fork/clone the UG repo, then write a recipe to generate a CrownAnki JSON file that combines the two decks, and finally import that JSON file into Anki.

Sounds like you'd like Brain Brew, if Markdown was added as a Source type. Currently has two way sync between Csv and CrowdAnki, and the conversion is all abstracted so that other source types can be added.

Brain Brew 🧠

About other shared decks, I was just made aware a few days ago that someone has taken inspiration from the Ultimate Geography Git repo, and started their own UK Geography deck using the same tools (and thus, Brain Brew, which is how I found out). https://github.com/HartBlanc/anki-uk-geography Looks like a good one!
