I have a list of identification codes that are five digit numbers but will
always be treated as text. For example,

'00020
'00015
'00025
'00050
'00035

I need a worksheet function that will tell me the MIN and MAX of these codes
(evaluating the text as numbers). In this example I know that MIN=00015 and
MAX=00050. However, the actual list will contain hundreds or thousands of
codes. I need the solution to be a function. Sorting or filtering to
manually find the MIN/MAX will not work for me. I'm sure I'm not the first
person to encounter this so I am hoping someone can help me. Thanks so much.
