How to generate an uuid in google sheet?

Question

How to generate an uuid in google sheet (for exemple ccb8a660-91c9-a556-58e0-4fa7-229516872004).

Either with a macro? or a formula?

Answer 1

I tried creating a pure sheet function that creates full uuid's just with sheet code and this is what I ended up with it's pretty silly but it does seem to work. It will re-generate every time the sheet updates so this might not be useful but I wanted to post it anyway because there wasn't a pure sheet implementation available.

=CONCATENATE(MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),"-",MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),"-",MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),"-",MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),"-",MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1),MID("0123456789abcdef",RANDBETWEEN(1,16),1))
