Why this tool exists
The UUID Batch Generator keeps identifier minting and checksum verification in one workspace so you can seed fixtures, issue API keys, and share batch evidence without swapping scripts.
Fixture seeding
Mint UUID batches for tests or migrations and hand QA the exact identifiers you generated.
Key distribution
Issue API keys or device identifiers and share the exact batch in onboarding docs.
Integrity audits
Attach checksums to every export so reviewers can prove nothing changed between systems.
Quick start
Generate UUID batches with the right version, casing, and formatting for downstream systems.
- Open the UUID Batch Generator and choose the UUID version that fits your workload.
- Set the batch size (1–50), letter case, and formatting style for the identifiers.
- Generate a batch, then copy the list or checksum table into tickets, runbooks, or seed files.
Supported inputs
- UUID generator accepts batch sizes from 1 to 50 per request with versions v4, v7, or ordered plus hyphenated or compact output.
- Switch between lower and upper casing to match consumers before copying a batch or exporting checksums.
- Checksum list covers MD5, SHA-1/256/384/512, and CRC32B for validating the entire batch.
Mode 01
UUID batch walkthrough
- Pick the UUID version that fits your workload: v4 for random identifiers, v7 for time-ordered rows, or Ordered for sequential inserts.
- Set the batch size within the 1–50 guardrails and choose hyphenated or compact plus the expected letter case.
- Click Generate batch to populate the output list and enable the “Copy batch” shortcut that strings every UUID with newline separators.
- Review the checksum table to share MD5, SHA, and CRC signatures so teammates can validate the entire batch without rerunning the tool.
Exports & verification
Copy-friendly controls keep UUID batches and checksum notes consistent between teammates.
- Use the “Copy batch” control to grab every UUID—perfect for `.env` variables, fixture files, or quick seed scripts.
- Checksum cards cover MD5, the SHA family, and CRC32B so you can paste them into release notes or compare against `shasum -a` output in your terminal.
Outputs & snippets
Every submission populates batch lists, checksum tables, and export-ready snippets so you can copy or script against them.
UUID batch output lists every identifier with individual copy actions plus a master batch copy.
Batch checksums provide uppercase algorithm labels with digests for MD5, SHA-1/256/384/512, and CRC32B.
Field notes
Keep deliveries audit-friendly and ready for verification.
- Lock casing and formatting before copying so the identifiers you ship match downstream expectations.
- Pair each shared batch with the checksum list so recipients can rerun shasum or certutil for instant verification.
- Chain this guide with Timestamp → Datetime when you need to timestamp UUID issuance and batch verification together.
