Hi @esai,
Thanks for getting in touch!
Yes, it is possible by using the product import/export feature to edit the product CSV file.
Please enter the wholesale prices, minimum order quantity and order quantity step to one or two products, first, to generate the wholesale meta fields on the CSV file.
Then, please proceed with the steps below:
1. Go to Products > Export
2. Check Export Custom Meta and click Generate CSV
3. Open your CSV file and look for the column for the wholesale price data key (check below for further information)
4. Save your file and upload it in Products > Import
5. Check Update Existing Products
6. Click continue and complete the importing process
7. Go to WooCommerce > Settings > Wholesale Prices > Help and click the Re-Initialize Product Visibility Meta
If you check WooCommerce > Wholesale Roles, you can see wholesale roles with the key. For example, the default wholesale role is Wholesale Customer with wholesale_customer as the key.
So when the wholesale role key is *wholesale_customer*, the meta key would be something like *wholesale_customer_wholesale_price*
{wholesale role}_wholesale_price
{wholesale role}_wholesale_minimum_order_quantity
{wholesale role}_wholesale_order_quantity_step
{wholesale role}_have_wholesale_price
I hope this helps. If you have any other questions, feel free to ask me again.
