Matrixify

If I could give this app six stars, I would! Shopify's interface for editing products and uploading sheets is horrible whereas Excelify makes it a breeze to do and massively reduces the chance of unforeseen errors occurring, I only wish I had found it sooner! The fact that you can also include an extra store under your plan is very useful if you are looking to expand. There are a wealth of tutorials and documentation provided by the developers, meaning it's really easy to get started and understand how everything works. This really should be a must-have for any Shopify merchant, thank you and keep up the good work!
