I need help transferring product and product category data from my website's SQL database to my Shopify store. The website is built on PHP, and the database contains structured product category information that needs to be extracted and imported accurately into Shopify. Please ensure the imported data works seamlessly with Shopify's system, maintaining the correct structure and format. Your experience with similar tasks is important, so please share examples of past work involving data migration to Shopify or similar platforms. This project needs to be completed as soon as possible, ensuring a smooth and efficient transition of the data.
