I wanted to do some stuff with Hearthstone cards, but first I needed to get them into a usable format. Searching web-based databases for cards using the filters they offer is just so tedious. I googled "hearthstone cards .csv" and found something that wasn't exactly what I wanted: Hearthstone Cards in JSON.
What I don't like about JSON is that I can't open it in a spreadsheet. What I do like about JSON is that with a few lines of code I can transmute it into something I can open in a spreadsheet.
Hearthstone Cards, Comma Separated
Click that link and you'll get a lot of selected text, ready to be copied and pasted into a text editor and saved as a .csv which will be recognized by your spreadsheet.
Now that I have this I should be able to figure some useful things out.
