I have successfully able to do bulk upload from Magento 2.0 admin panel IMPORT options.But My requirement to do bulk uploads of products with script.
Is there any customizable script provided by magento 2.0 for bulk upload.
For upload all the product using script you need to manually create import script. Magento out of the box doesn't give any script for upload product. They give only import/export option using csv/xml from backend.
