A good way to organize and protect Named Ranges in Excel is to place all of them on a separate  worksheet. This sheet can then be protected and also hidden from view (but the named ranges still work)
An added bonus is the ability to copy this sheet to a new workbook so all your named ranges are ready for use. Excel training Toronto, Ontario
