UUID Generator Overview
This online UUID generator can batch-create UUID v4 and GUID identifiers for order numbers, database primary keys, API trace IDs, device IDs, and distributed data correlation. It supports hyphen toggle, case switch, and TXT download for fast bulk generation under different business rules.
Core Features
- Batch generation supported, up to 2000 UUIDs per run.
- Choose hyphenated or non-hyphen UUID output for schema compatibility.
- Upper/lowercase output supported for consistent signatures and logs.
- One-click copy and TXT download for quick import into code, test data, or config files.
Usage Tutorial
- Enter the required count in “Generation Quantity”.
- Toggle “Keep Hyphen” and “Uppercase” as needed.
- Click “Generate UUID” to get results and see real-time status/count.
- Use “Copy Result” for code/docs, or “Download TXT” to save locally.
Scenarios and Advantages
UUID/GUID is widely used for microservice tracing, database unique keys, e-commerce order systems, activation codes, and API request IDs. Compared with manual ID assembly, this tool lowers duplication risk, improves efficiency, and reduces sensitive-data transfer risk via local processing.
FAQ
What is the difference between UUID and GUID?
In most development contexts, they are considered the same type of globally unique identifier, mainly differing by naming convention.
Why do some UUIDs have hyphens while others do not?
Hyphenated UUIDs are easier to read, while non-hyphen ones are more compact. Choose based on DB field length or API protocol.
Can generated results be exported in bulk?
Yes. Click “Download TXT” to export current batch UUID results for archiving or secondary processing.
