Copying my answer from the website, but this can be done by extremely nontechnical people:1) Copy all of the JSON data.2) Paste it into this link: http://konklone.io/json/ (I don't know if this is cheating)3) Download the file.3a) If it opens in a new page, just manually save the source as a .csv4) Open it in excel.5) Click the column of credit cards.6) Click the button to sort in descending order.7) Scroll down to the point where you run out of credit cards.8) Delete everything after that.
