UUID Toolkit

Generate, parse, validate, and convert UUIDs, ULIDs, and NanoIDs. Zero dependencies (Python 3.9+).

Quick Start

# Generate a UUIDv4
python3 scripts/uuid_toolkit.py generate uuid4

# Generate 10 ULIDs
python3 scripts/uuid_toolkit.py generate ulid --count 10

# Parse a UUID
python3 scripts/uuid_toolkit.py parse 550e8400-e29b-41d4-a716-446655440000

Commands

generate

Create identifiers of any type:

python3 scripts/uuid_toolkit.py generate uuid4                      # Random UUID
python3 scripts/uuid_toolkit.py generate uuid1                      # Time-based UUID
python3 scripts/uuid_toolkit.py generate uuid5 --name example.com   # Deterministic
python3 scripts/uuid_toolkit.py generate ulid                       # Sortable ULID
python3 scripts/uuid_toolkit.py generate nanoid --size 16           # Short NanoID
python3 scripts/uuid_toolkit.py generate uuid4 --count 100 --upper  # Bulk, uppercase
python3 scripts/uuid_toolkit.py generate nil                        # Nil UUID

Types: uuid4, uuid1, uuid3, uuid5, ulid, nanoid, nil.

parse

Extract detailed info from an identifier:

python3 scripts/uuid_toolkit.py parse 550e8400-e29b-41d4-a716-446655440000
python3 scripts/uuid_toolkit.py parse 01ARYZ6S41T1ZTXYZ1234ABCDE  # ULID

Shows version, variant, timestamp (v1/ULID), node/MAC (v1), hex, integer.

validate

Check if identifiers are valid:

python3 scripts/uuid_toolkit.py validate 550e8400-e29b-41d4-a716-446655440000 not-a-uuid

convert

Convert UUID between representations:

python3 scripts/uuid_toolkit.py convert 550e8400-e29b-41d4-a716-446655440000

Outputs: standard, uppercase, no-dashes, URN, integer, base64, bytes-LE, braces.
