Frequently asked questions
v4 or v7?
v7 embeds a timestamp so IDs sort by creation time, which keeps database indexes efficient. v4 is fully random.
How random is it?
Values come from crypto.getRandomValues, a cryptographically secure generator.
Can I export as JSON?
Yes. Copy the list one per line or as a JSON array.
