Generate thousands of UUIDs at once and export them as TXT, CSV or JSON.
Optional, e.g. user_ for self-describing identifiers.
Test fixture
A hundred identifiers
100Database seed
One thousand keys
1000Large batch
Ten thousand at once
10000Up to ten thousand. Version 4 for general use, version 7 when the identifiers will be database primary keys.
Plain text for pasting, CSV for a spreadsheet, or JSON for code and fixtures.
Copy the lot to the clipboard, or download a file ready to import.
Ten thousand identifiers generate in well under a second, which turns seeding a test database into a single step.
CSV with a header imports straight into a spreadsheet; JSON drops into a fixture file without reformatting.
Time-ordered identifiers keep index inserts sequential, avoiding the write amplification random keys cause on large tables.
Built for volume. Where the standard UUID generator suits copying one or two identifiers, this one produces up to ten thousand in a single pass and exports them in the format your next step expects — plain text, CSV with a header row for spreadsheet import, or a JSON array for seeding a database. Version 4 for pure randomness or version 7 for time-ordered keys that keep database indexes healthy. Everything is generated in your browser using the cryptographic random source.
