Matrixify

I would give this 10 if I could! We went live with 1500 skus and no way would it have been possible with the Shopify csv upload.
Support is absolutely amazing, Maris is responsive, thinks about what you are trying to achieve and is a delight to work with.
Tutorials are clear and extensive. Works with basic data plus metafields, all collections, Google data feeds...everything you can think of, even multiple image loading.
A must have app!

1. YOU CAN CONVERT EXISTING PRODUCTS INTO A VARIATION!
2. BULK DELETE using a CSV file. Was able to delete 10,000 products in one upload omg. <3

Incredibly useful app for accessing fields the standard import/export doesn't touch. The developers are super timely and knowledgable. The support chat feature is great. I'd give ten stars if I could.

Amazing app. Was super useful to bulk update price changes, publish dates and contacts when we migrated to shopify. Customer support was exceptional! Highly recommend!

The first app that I install when helping clients on a new shopify account!

I have been using the application for a few months and this is the easiest way to bulk change my product catalog. I can export very specific grouping of products, make a couple quick edits, and reupload quickly. This makes it easy to do a price reduction for a sale, page template changes, tag changes, name reformatting, product duplications, and even backups of archived products to remove them from my store seasonally. Recently, I restructured some of my store because of some SEO and needed to create 100+ dynamic collections. It was amazingly simple and quick with this app. Simple to use, and errors are easy to identify. I even use it to sync to a demo store for dev work and changes.

I have lost track of the countless times Excelify has saved my bacon with migrating content, setting tags, editing old links, creating 301's you name it. Added to this their support is amazing and they are genuinely interested in our success. Just install the app, do it.

Best Shopify app I have used. Direct sales order migration from a Woo site was extra helpful. After thorough research I didn't find any feasible alternatives to buying a subscription to this app for our data migration needs.

The app is as good as people behind it... 5 stars ! It's really nicely designed and the support team is the kind of people you'd like to have in your own team. Great job !

One of the indispensables if you run a shopify with thousands of products
