Random v4 or time-ordered v7 identifiers
Make version 4 or version 7 identifiers, from 1 to 1000 at a time. Randomness comes from crypto.getRandomValues only. Uppercase and removing hyphens reformat the list you already have. A GUID is the same idea. Nothing is uploaded.
v4 random, or v7 ordered by time
v4 is random. v7 starts from the current time so the values sort by when they were made. Quantity runs from 1 to 1000, and each value uses crypto.getRandomValues.
Reformat without rolling new ones
“Uppercase” and “Without hyphens (32 hex characters)” change the current list. They do not call “Generate” again. People also say GUID for this kind of id.
How to generate UUIDs in the tab
-
Leave v4 for random ids. Choose v7 when the ids should sort by time.
-
Type a number from 1 to 1000.
-
Press “Generate”. The values come from crypto.getRandomValues only.
-
Turn on “Uppercase” or “Without hyphens (32 hex characters)” to restyle this list. That does not generate a new batch.
Ids made in the tab, then restyled
-
v4 is random
Use v4 when you do not need the ids to sort by time.
-
v7 is time-ordered
v7 puts the time first, so newer ids sort after older ones.
-
crypto.getRandomValues only
The page does not use another random source.
-
1 to 1000
One press can fill a short list or a long one, inside that range.
-
Restyle the current list
Uppercase and no hyphens rewrite what is already on screen.
-
GUID means this idea
A GUID is another name for this kind of identifier, not a second generator.
Questions about the UUID generator
What is the difference between v4 and v7?
v4 is random. v7 is time-ordered, so the ids sort by when they were created.
How many can I make at once?
From 1 to 1000.
Where does the randomness come from?
crypto.getRandomValues only.
Does Uppercase create new ids?
No. It reformats the current list, and so does removing hyphens.
Is a GUID something else?
No. A GUID is the same idea as these identifiers.
Are the ids uploaded?
No. They are generated in this tab.
