If you're connecting Zentail to your BigCommerce store for the first time, it's helpful to have a backup of your BigCommerce data.
Here's how to generate a bulk export from Bigcommerce:
1. Go to Products › Export.
2. Select your export settings.
Template — Select your export template. Bulk Edit is recommended if you are not using a custom export template.
File Format — Zentail recommends the CSV format.
3. Click Continue, then click Export my products to a CSV file in the pop-up window.
4. When the export is complete, select Download my Products file. The file will be saved to your computer, usually in your Downloads folder.
