Custom Script to get Aliexpress Product info into Json Array

I want to get a very simple job done. Get me the Aliexpress product information into a json array (make sure your json must be valid.) I want to have all of these details from this script. Product Title, URL, Description, Images, All product Variants along with their variations details like price, images etc. And the entire bunch of details into a valid json array. That's it. Thanks !
