This tutorial demonstrates how to migrate content from an HTML page in a WordPress site to Contentful using ChatGPT. It outlines the steps necessary to create a migration engine between an HTML page and Contentful, including creating API tokens for both platforms, setting up Node.js dependencies, and defining services for data extraction, sanitization, and interaction with ChatGPT and Contentful APIs. The tutorial showcases how to use OpenAI's GPT-3.5-turbo model to rewrite the HTML content as a Contentful document object, and how to orchestrate the migration process using Node.js. The outcome is a fully functional migration engine that can accelerate data migration from legacy systems to Contentful.
