excel UUID

A UUID (Universally Unique Identifier) is a 128-bit number that is unique across all devices and networks. In Excel, you can generate a UUID using a formula. Here's how:

1. Open a new Excel worksheet.
2. In cell A1, enter the formula =CONCATENATE(DEC2HEX(RANDBETWEEN(0,4294967295),8),"-",DEC2HEX(RANDBETWEEN(0,42949),4),"-","4",DEC2HEX(RANDBETWEEN(0,65535),4),"-",DEC2HEX(RANDBETWEEN(16384,20479),4),"-",DEC2HEX(RANDBETWEEN(32768,49151),4),DEC2HEX(RANDBETWEEN(0,65535),4),DEC2HEX(RANDBETWEEN(0,65535),4)).
3. Press Enter to generate the UUID.

The formula generates a random UUID in the format xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx, where x represents a hexadecimal digit (0-9, A-F) and y is either 8, 9, A, or B. The formula uses the RANDBETWEEN function to generate random numbers and the DEC2HEX function to convert them to hexadecimal. The CONCATENATE function combines the hexadecimal strings into the UUID format
