Function to Decapitalize Fields

Function to Decapitalize Fields



I imported a Zip code data into a "Zip Code" custom module in CRM, in order to auto assign leads to sales reps. Is there an easy way for me to mass change the data to make it not capitalized? Instead of LOWER PEACH TREE, to change to Lower Peach Tree and so on?
I dont wanna go through the trouble of canceling the import, changing the data in excel and doing it again, there are almost 50,000 records.
