What file format does Google Merchant Center accept?

Tab separated text (.txt or .tsv), CSV, XML and Google Sheets. Tab separated text is the simplest and avoids problems with commas inside descriptions, so it is this tool’s default.

Can I use my Shopify product export?

Yes. Export products as CSV from Shopify, add your website address, and the tool builds each product link from the handle, fills variant rows from the main row and turns compare-at prices into sale prices.

Does it work with WooCommerce?

Yes. Export products from WooCommerce as CSV. Columns such as SKU, Name, Regular price, Sale price, In stock? and Images are matched automatically.

Why are my GTINs being rejected?

A GTIN has a check digit, and many feeds contain made-up or mistyped barcodes that fail it. The tool checks each one and leaves out invalid barcodes so the product can still be approved.

Is my product data uploaded anywhere?

No. The file is read and formatted in your browser and the download is made on your computer. Nothing is sent to a server.
