It generates duplicates for large numbers of UUIDS (14 500 of them) in osx, I ran it 5 or 6 times and there were around 8 duplicates each time.

Also it is recalculated everytime

I get #NUM! errors one in every few thousand calculations of this formula.

Here is why:

  • POWER(16;4) returns 65536.
  • RANDBETWEEN is inclusive of the 'bottom' and 'top' values.
  • DEC2HEX(65536;4) throws the NUM error as its needs 5 characters; the highest value DEC2HEX can return in 4 characters is 65535
  • So the POWER() function is giving a 'top' bound to the RANDBETWEEN that is exactly 1 too high.

The fix is to add -1 after each use of the POWER() function in the formula:

=LOWER(CONCATENATE(DEC2HEX(RANDBETWEEN(0;POWER(16;8)-1);8);"-";DEC2HEX(RANDBETWEEN(0;POWER(16;4)-1);4);"-";"4";DEC2HEX(RANDBETWEEN(0;POWER(16;3)-1);3);"-";DEC2HEX(RANDBETWEEN(8;11));DEC2HEX(RANDBETWEEN(0;POWER(16;3)-1);3);"-";DEC2HEX(RANDBETWEEN(0;POWER(16;8)-1);8);DEC2HEX(RANDBETWEEN(0;POWER(16;4)-1);4)))

Just one question... The GUID's get refreshed evertime I do something to the column or near the column that contain the formula. Is there a way to just generate it once and fix the generated GUID's?

Regards, Arie

I set one cell in excel to be my UUID generator using the formula and naming the range, then I use VBA to refer to the named range when I want to commit the value to a stored location using something like:

For Each rRecord In rNewRecords
     rRecord.Offset(0, -1).Value = [r_uuid].Value
     [r_uuid].Calculate
Next rRecord

Where r_uuid is a named range in the workbook.
