ExportingSquarespace to other Sales Plaforms

Site URL: http://www.ancientwisdomcurations.com

I am suprised that I cannot get an answer from Squarespace on how to export all the products and have them SUCCESSFULLY IMPORT to another platform like ETSY, Facebook Marketplace, Ebay, Amazon, and other large platforms.

I use my website to putt all my product on initially with the hopes of being able to export them to other sites.  Problem is they export fine, but are not accepted for one reason or another by other platforms.

I can't be a best practice to retype all of the pictures and data for every sight.  This is 2021, not 1989.  So, what are we supposed to do to successfully export and import.  It's obvious that Squarespace Customer Support doesn't know, so I was hoping for some guidance.....

Thanks,
