Ecommerce Website with Wishlist – Google Sheets Apps Script

An online store that keeps its whole catalog in Google Sheets. Products, categories, prices and stock are rows in a sheet; the storefront reads them and customers browse, save and order from a normal shopping interface. No hosting, no database server, no monthly platform fee.

What it does

Customers browse by category and sub-category, rate products, and add anything they like to a wishlist. From the wishlist an item moves straight into the cart, which is the step most spreadsheet-built stores skip — a saved item that cannot be bought in one click is a lost sale. Stock is respected automatically: when a product's stock reaches zero it disappears from the storefront instead of taking orders you cannot fill. Orders are written back to the sheet, so the shop owner works in one place.

Highlights

• Wishlist, with one-click move from wishlist to cart
• Shopping cart and order placement
• Product ratings on every item
• Out-of-stock products hide themselves from the storefront
• Category and sub-category filtering
• Catalog and orders both live in Google Sheets
• Mobile responsive storefront

Who it is for

Small shops, home businesses and anyone testing a product line who wants a working storefront without committing to a hosted e-commerce platform. It also makes a clear reference build if you want to see how Google Apps Script handles a catalog, a cart and stock rules on real data rather than a demo.
