How to create a GUID in Excel?

I need a function to add a GUID to cells in excel. I found this previous question on stackoverflow, but it is not working. It suggests the following function:

=CONCATENATE(DEC2HEX(RANDBETWEEN(0,4294967295),8),"-",DEC2HEX(RANDBETWEEN(0,6553‌​5),4),"-"
    ,DEC2HEX(RANDBETWEEN(16384,20479),4),"-",DEC2HEX(RANDBETWEEN(32768,49151‌​),4),"-"
    ,DEC2HEX(RANDBETWEEN(0,65535),4),DEC2HEX(RANDBETWEEN(0,4294967295),8))

I have been unable to get the concatenate method to work, and so tried it using the "&" figure to concatenate anyway. That seemed to work, but then I get an inexplicable error on the second DEX2HEX block: DEC2HEX(RANDBETWEEN(0,6553‌​5),4). The Excel formula evaluator says it's invalid, but I can't seem to figure out why at all. Any ideas?

Solution

  • I am using the following function in v.2013 excel vba macro code

    Public Function GetGUID() As String 
    GetGUID = Mid$(CreateObject("Scriptlet.TypeLib").GUID, 2, 36) 
End Function
