Ablestar Bulk Product Editor

This is exactly the app I've been searching for. Tried some other bulk editors, but they had significant limitations: no changes preview, no undo, very clunky Shopify product sync & didn't work with metafields unless you upgraded to a much more expensive plan. This app works with all fields, even metafields.

Before you run the edits, you can scan the pending changes and quickly spot any errors in your filtering that'd adversely affect some products by your changes.

Can also use the filters to explore bulk product updates that you weren't aware were needed, such as blank data fields that shouldn't be empty.

So far, I've only used the in-app updates - not the extensive spreadsheet options - as the in-app options have so far met all my needs.
