Matrixify

Life saving app, allows us to import large amounts of stock relatively painlessly once spreadsheet configs are set up and working.
Metafields management is a big thing for us which Shopify's native import really cannot handle. We also use it every day to run picksheets too. Its really good, and most importantly support is really top notch.

If I could give this app 10+ stars I would! There are other apps which aid in a migration, which is what I used this for, but the other apps aren't very mature in terms of being able to capture ALL the data. The other problem is that the data has to sit somewhere while being migrated (on other apps). If you just export (on the old store) to all the defaults and import (to the new store) using this app on both stores, you'll see it does an INCREDIBLE job! I was extremely impressed.. you can export metafields and weird data chunks that you wouldn't think you needed - but you do - when migrating. A must-have App for that activity. It's also useful as a backup too - I see other backup systems out there, but this one would work great to keep a copy of your data locally should something bump into your store.

Amazing tool, allows you to upload and download metafield objects, merge tags and so much more. Setup of the files is easy and the documentation is helpful. A must have for all stores that upload in CSV/Excel.

The support team has been so amazing at addressing any roadblocks or issues that come up. The tool is amazing but we use it in a very specific way, and they have been extremely quick to troubleshoot and problem solve with me. As the CEO of the company, I really appreciate their service and customer support.

Matrixify performs its function beautifully and the support staff have always been responsive and friendly. We highly recommend this app for handling any larger data imports and exports: an area where's Shopify's native functionality can be extremely limited.
