Bulk Update Vendor Name WooCommerce

Hi,

Was wondering how to bulk update the Vendor Name in Products of WooCommerce.
Tried the Bulk Actions > Edit > Vendor Username, but when updated, there were no changes reflected. Even already had a column on the CSV file that has the ‘vendor username’ column, but it still doesn’t work :frowning:

It would be updated though if you go through the products one-by-one :disappointed:

thanks in advance!
