SPARKLN review for Mixtable Spreadsheet Editor

Without Mixtable I have no idea how would I be able to handle thousands of products at once as Shopifiy's product editing platform does not support things like: filtering in metafields, filtering and adding tags accurately(Shopify's product search is RUBISH, not accurate), assigning/removing products to collections... there is so so many things that you can do here!... in Shopify you can only search in the product description and based on that you can add tags or assign them to collection but in most cases the info you need won't be in the description... This product is so underrated... 10 STARS!!!
