I have export product from backend and getting custom product attribute but it shows empty data in csv file. does anyone know how i can export custom attribute with value?
In default Product Export, all custom attributes get appeared under "additional_attributes" header in the export separated by a comma (,). Please check CSV file again.
And one more thing you can use this free module: https://bsscommerce.com/custom-product-attribute-export-for-magento-2.html
It is a very useful extension for this problem.
