Mixtable Bulk Editor

The absolute BEST money we spent on store setup.
If you have bulk editing to do, get this app immediately. The app really shines in its ability to edit almost anything about your product. Bulk editing of simple things such as categories is great, sure. But the spreadsheet functionality is just insanely helpful. Add columns just to store data, run formulas, combine columns . . . it's unbellievable. And then sync it up and seconds later your whole store is up to date. And even more (yes, there's more), you can edit other content that is impossible to do elsewhere, such as metafields! This alone is just a slam dunk. It's impossible to overstate how amazing this app is if you have lots of editing to do.
