The orders spreadsheet is not designed to show you how many sales were made on each individual product, but there’s another option:
Sales Report
If what you’re looking to get is a sales report for all your products or individual products, we suggest you use the native WooCommerce Reports.
Find it under WooCommerce > Reports
Spreadsheet for WooCommerce Products
Our spreadsheet for products allows you to see a table containing all your products, and it includes a column called “Total Sales” where you can see the all-time sales per product.
