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?

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 

Generate a GUID in Excel, I often generate the SQL using Excel as it makes it easy to duplicate the common parts of the scripts, but there is no built in GUID generator in Excel. Fraxture's solution (no offense) does not even create a valid guid as it doesn't take things such as the current time, MAC address, etc. into account. They also won't include the guid version bit. Guids are not just a set of random characters, there is meaning behind them.

As of modern version of Excel, there's the syntax with commas, not semicolons. I'm posting this answer for convenience of others so they don't have to replace the strings- We're all lazy... hrmp... human, right?

=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))

Or, if you like me dislike when a guid screams and shouts and you, we can go lower-cased like this.

=LOWER(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)))

Alternative to GUID in Excel, Excel GUID auto generate primary key.Duration: 2:41 Posted: Jul 17, 2016 Step 2 – Exploration. Step 3 – Execution. Step 4 – Cleanup. Step 1 – Setup in this function is essentially just our variable declarations and assignments on lines 6-19. We create an Object variable, obj, which will be assigned to the built-in Scriptlet.TypeLib object, and a String, strGUID, which will contain the GUID.

This is not a problem with the function at all.

It took me a bit of digging, but the problem is in copying and pasting. Try copying this: RANDBETWEEN(0,6553‌​5) string, posted in your original question, and paste it into a Hex Editor, then you'll see that there are actually two null characters in the 65535:

00000000  52 41 4E 44 42 45 54 57 45 45 4E 28 30 2C 36 35  RANDBETWEEN(0,65
00000010  35 33 00 00 35 29                                53‌..​5)

  • Why not just use the VBA code supplied in the same question?
  • Which version of Excel are you using? AFAIK RANDBETWEEN was only introduced in 2007. If you use 2003, replace it with INT(RAND()*65535)
  • @PeterAlbert but then I get an inexplicable error on the second DEX2HEX block - assuming that 1st block is ok)
  • @PeterL.: Not sure I understand your comment... :-(
  • I suppose I don't have to point out that this doesn't generate "real" GUIDs - because they have no version number. See en.wikipedia.org/wiki/Globally_unique_identifier for details
  • couldnt get PeterL's solution to work in Excel 2013.. and after a total of 10 seconds of debugging the function, I found your solution to be a better fit for me. Works perfect. thanks!
  • This should be used instead of Frazture's answer because it is much more straightforward and relies on the system to generate the guid. Fraxture's solution (no offense) does not even create a valid guid as it doesn't take things such as the current time, MAC address, etc. into account. They also won't include the guid version bit. Guids are not just a set of random characters, there is meaning behind them. More info here: en.wikipedia.org/wiki/Globally_unique_identifier#Algorithm

  • I confirm @Radek 's comment that after a security update to Office, this mechanism no longer works. stackoverflow.com/a/45332789/575559 documents the Microsoft recommended methods to prevent the above function from causing a "permission denied" error OR to make use of an alternative function.
