The website reads its catalogue from a Google Sheet with five tabs. Start from the template files, convert your Etsy export into the products and colours tabs below, then paste the sheet ID into the website’s sheetId setting.
Connecting the sheet1. Create a Google Sheet with five tabs named exactly products, colours, rooms, creators, settings. In each tab, use File → Import → Upload and pick the matching CSV (choose “Replace current sheet”).2. Share → General access → “Anyone with the link” as Viewer.3. Open config.json in the website folder and paste the sheet’s full link between the quotes of "googleSheet". With it left empty, the site reads the CSV files in the data folder instead.Photos are file names inside assets/products/ (cutouts in assets/cutouts/, room images in assets/scenes/). Full https:// links also work. Separate multiple values with a semicolon.
