Extract Amazon orders to a csv file

extract-orders.js

// Simply copy and paste this entire snippe into the browser console (Cmd + Option + J opens the console) from the Amazon orders page (https://www.amazon.com/gp/css/order-history?ref_=nav_AccountFlyout_orders)
// For now you'll have to navigate to the next page yourself and re-run this on each page.
// Once you've finished running this on all relevant order pages, run the following:
//
//
// const storedData = localStorage.getItem('amazonOrdersCSV');
// downloadCSV(storedData); 
//
