Kindle Library Exporter – Export Kindle Library as CSV from read.amazon.com

kindle-library-exporter.js

/**
 * 📚 Kindle Library Exporter + ISBN Lookup 📚
 * 
 * This script extracts book data (ASIN, Title, Authors) from https://read.amazon.com/kindle-library
 * and searches for ISBN using Open Library API. The data is exported as a CSV file.
 * 
 * 🚨 IMPORTANT: YOU MUST USE GOOGLE CHROME 🚨
 * 🛑 Why Google Chrome? 
 * - Amazon Kindle Library uses advanced security restrictions.
 * - Other browsers (Firefox, Edge, Safari) may block access to book data due to security policies.
 * - Google Chrome allows us to extract book metadata safely using the DOM.
 * 
 * ⚠️ IMPORTANT INSTRUCTIONS: READ BEFORE RUNNING ⚠️
 * 1️⃣ Open **Google Chrome** and go to **https://read.amazon.com/kindle-library**
 * 2️⃣ **Manually scroll down** until you reach the end of your Kindle Library
 * 3️⃣ **Ensure all books are loaded and visible on the page**
 * 4️⃣ **Click anywhere on the page** to ensure focus
 * 5️⃣ Press **F12** (Windows/Linux) or **Cmd + Option + I** (Mac) to open Developer Tools
 * 6️⃣ Click on the **"Console"** tab
 * 7️⃣ Copy & paste this script into the console and press **Enter**
 * 8️⃣ A file named **'kindle_books.csv'** will be downloaded automatically

This script is great. Almost perfect. I wonder how hard it would be to add the Publish Year and number of pages to the script. Both are listed on OpenLibrary.

Glad to hear it! I’ve since moved over to Kobo and Komga, so I no longer really keep up with what’s going on in the Amazon and Kindle ecosystem.
