How can I bulk upload metafields for SKU, UPC and item condition?

[RichMag33]

I would like to add my SKU, UPC and item Condition to my product page.  Because I have thousands of products I really need to be able to upload these items when I bulk add (csv) new products.  I have attached a screen shot of what Im trying to do.  Was wondering if Metafields is the only way which, from everything ive read, isnt possible to bulk upload without the use of an app.  Any other options?  Picture is in the reply section.

Thanks,

Rich

Have you found a solution. I've been going at this for more than a week and haven't found a solution yet, whether it's through import/export, bulk edit, or apps. Would be appreciated if you can share your experience. Thank you.

Shopify has added import/export of metafields in their latest update.

Shopify has finally added bulk export and import of product metafields in the Summer 2024 update. No need for apps or workarounds now.
