In products like business cards or promotional posters, shoppers may want to fill in data that are already available elsewhere, for example, a list of employees with their name, job title and contact details. The autofill feature allows you to link a spreadsheet containing data to a customizable product. This way shoppers only need to select a record and the details are inserted automatically. This feature can also be used to automatically insert product specifications and prices in a sales document or populate data sheets, saving time, reducing the risk of errors, and eliminating typos. This is done by uploading an Excel file, which works together with the uploaded StoreFront package, when you create your customizable product.
