Updating of Products & Add-ons in bulk via csv

The Site is currently not live.
We are running Woo-commerce version 4.9.2 on Word Press 5.6.2
and WooCommerce product add-ons

I am looking at being able to export/import all products and their associated add-ons (accessories) with the view of updating prices. We deal with different manufacturers with different discount structures so some of the already built in features are too simplistic.

I am aware I can export/import products as a csv file and that will work for pricing etc..But it’s the add-ons etc… that is the issue. I have just discovered that I won’t be able to do this with the current wooCommerce add-on plug in so any suggestions to alternative add-on plug in would be appreciated.

I am fairly new to the WordPress software and plug-ins so despite having done some research I am struggling to find a solution.

Thank you in advance for any assistance, Kind regards Jane
