If you can’t see the variations on your CSV file, there are 2 possible reasons why this happened:
1- You didn’t click on “display variations” in our spreadsheet toolbar before starting the export. Make sure the variations are showing on the live spreadsheet before exporting because our exporter will include the rows that you see in the live spreadsheet.
2- We’ve seen some scenarios where not having the latest WooCommerce version prevents the plugin from exporting the variations, please make sure you have the latest WooCommerce Version.
