Bulk UUID & GUID Generator
Instantly generate up to 10,000 cryptographically secure UUIDs. Export perfectly formatted mock data for your databases.
About The Bulk UUID / GUID Generator
Universally Unique Identifiers (UUIDs) are 128-bit numbers used in software development to uniquely identify information in databases, distributed systems, and APIs. Generating them one by one is tedious, especially when mocking large databases.
This bulk generator allows developers to instantly create up to 10,000 cryptographically secure UUID v4 strings in a single click. It utilizes the modern 'crypto.randomUUID()' browser API to ensure absolute uniqueness. You can customize the output format by stripping hyphens or wrapping the identifiers in quotes for easy pasting into JSON arrays or SQL insert statements.
How to Use
- Enter the number of UUIDs you want to generate (up to 10,000).
- Toggle the format settings: choose whether to include hyphens or wrap the strings in quotes.
- Click 'Generate UUIDs'.
- Click the 'Copy' button to grab the entire list for your database or code.
Frequently Asked Questions
What version of UUID does this tool generate?
The generator creates UUID v4 (Version 4) identifiers, which are entirely randomly generated rather than being based on time or MAC addresses.
Are these UUIDs guaranteed to be unique?
Yes. The probability of a collision (generating the exact same UUID twice) with UUID v4 is so astronomically low that it is practically impossible in a single lifetime.
Can I format the UUIDs for a SQL query?
Absolutely. You can use the toggles to strip out the hyphens or wrap the identifiers in single quotes, making them ready to paste directly into a database IN clause.
