CSV Challenge
Copying my answer from the website, but this can be done by extremely nontechnical people:<p>1) Copy all of the JSON data.<p>2) Paste it into this link: <a href="http://konklone.io/json/" rel="nofollow">http://konklone.io/json/</a> (I don't know if this is cheating)<p>3) Download the file.<p>3a) If it opens in a new page, just manually save the source as a .csv<p>4) Open it in excel.<p>5) Click the column of credit cards.<p>6) Click the button to sort in descending order.<p>7) Scroll down to the point where you run out of credit cards.<p>8) Delete everything after that.
