In your WooCommerce setup, navigate to WooCommerce > TradeGecko. Click on the Export/Import tab.
Click on "Import Products from CSV" and select the exported CSV from Step 1.
Click "Upload file". If the upload is successful, you should see the page below.
Unless you want to create all products as variable products, you can skip the option and proceed by clicking "Import Attributes". You should then see another page like this.
