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.

For Spanish-MX Excel

=MINUSC(CONCATENAR(DEC.A.HEX(ALEATORIO.ENTRE(0,POTENCIA(16,8)),8),"-",DEC.A.HEX(ALEATORIO.ENTRE(0,POTENCIA(16,4)),4),"-","4",DEC.A.HEX(ALEATORIO.ENTRE(0,POTENCIA(16,3)),3),"-",DEC.A.HEX(ALEATORIO.ENTRE(8,11)),DEC.A.HEX(ALEATORIO.ENTRE(0,POTENCIA(16,3)),3),"-",DEC.A.HEX(ALEATORIO.ENTRE(0,POTENCIA(16,8)),8),DEC.A.HEX(ALEATORIO.ENTRE(0,POTENCIA(16,4)),4)))
