Inventory reports when exported should have a column including the Category on the Items sheet. That way you can sort by category when looking through your inventory. The example and issue I can give was trying to make a sheet that reported inventory so we can check said inventory. Because the items can't be organized by category and have the quantity column on the same page, you have to manually sort through each item one by one. Having to go through every item one by one and then making a new sheet with the information you need is inefficient.
