Source:
There is also VBA in the source above, but the simplest would be with the formula below, the only problem being that it changes every time the sheet is recalculated:
=CONCATENATE(DEC2HEX(RANDBETWEEN(0;4294967295);8);" ";DEC2HEX(RANDBETWEEN(0;42949);4);"-";DEC2HEX(RANDBETWEEN(0;42949);4);"-";DEC2HEX(RANDBETWEEN(0;42949);4);"-";DEC2HEX(RANDBETWEEN(0;4294967295);8);DEC2HEX(RANDBETWEEN(0;42949);4))
VBA solution below - paste into a regular module
Option Explicit
Public Function CreateGUID(Optional IncludeHyphens As Boolean = True, _
Optional IncludeBraces As Boolean = False) _
As String
Dim obj As Object
Dim strGUID As String
'Late-bind obj as a TypeLib -- a rare time when late-binding
'is actually a must!
'
'No matter how much experimenting I did, the Scriptlet object
'could simply not be pummeled into creating a GUID without
'a run-time error... See more discussion here:
'
'https://groups.google.com/forum/#!topic/microsoft.public.scripting.wsh/DWUq-tRLsOo
'
'All the way back to '99!
Set obj = CreateObject("Scriptlet.TypeLib")
'Assign the raw GUID, minus the last two erroneous chars
strGUID = Left(obj.GUID, Len(obj.GUID) - 2)
'If IncludeHyphens is switched from the default True to False,
'remove them from the GUID
If Not IncludeHyphens Then
strGUID = Replace(strGUID, "-", vbNullString, Compare:=vbTextCompare)
End If
'If IncludeBraces is switched from the default False to True,
'leave those curly braces be!
If Not IncludeBraces Then
strGUID = Replace(strGUID, "{", vbNullString, Compare:=vbTextCompare)
strGUID = Replace(strGUID, "}", vbNullString, Compare:=vbTextCompare)
End If
CreateGUID = strGUID
End Function
Public Sub TestCreateGUID()
'Dim t As Scriptlet.TypeLib <~ error, user type not defined
'Dim t As Scriptlet.IGenScriptletTLib <~ at least compiles
'Debug.Print t.Name <~ error, object or with block variable not set

Dim GUID As String
