Tool Usage

Return to old version

Set parameters first, then generate results

Configure quantity, UUID version, mobile device traits, and output format in order. After generation, only the first 20 items are previewed; copy and download include all results.

Generated locally v1 / v4 / v7 / v8 Brand and region traits TXT / CSV / JSON

Parameters

Load sample parameters first or generate once with defaults, then adjust quantity, version, and device traits for your test scenario.

Base quantityMax 10000 per generation

Quantity

Custom quantity

Preview and copy format

UUID versionMultiple selection allowed; the system assigns them randomly

Device brand Mobile device UUIDs and metadata use these device traits

Region & platform Select multiple regions; platform affects mobile device UUID fields

Target platform

Custom region code Added to region options; for internal tests or specific country codes.

Software Usage Instructions

Set the generation quantity: Select the number of UUIDs to generate, from 10 to 10000 entries, or enter a custom quantity. It is recommended to generate once using the default parameters first, then adjust according to your test scenario.
Select the UUID version:
- UUID v4: Random UUID format, suitable for general test data generation.
- UUID v7: Includes time-ordering characteristics, suitable for scenarios that require sorting or tracking generation time.
- UUID v1: Generated based on time and a random node identifier, suitable for compatibility with legacy systems.
- Mobile Device UUID: Uses the UUID v8 custom format, combining brand, platform, region, and channel characteristics.
Configure device characteristics: Select phone brands such as Apple, Samsung, Xiaomi, Huawei, OPPO, and Vivo. Multiple brands can be selected at the same time, and you can set the target platform, region code, and app channel.
Configure output options:
- Deduplicate during generation: Check against the final output format and avoid duplicates.
- Include device metadata: Export brand, model, platform, system version, region, and channel information.
- Uppercase letter format: Convert hexadecimal letters in UUIDs to uppercase.
- Remove hyphens: Output a compact 32-character UUID format.
- Add braces or quotes: Suitable for pasting into configurations, arrays, or SQL statements.
Save or load settings: Frequently used parameters can be kept by clicking “Save Settings”. The next time you use the tool, click “Load Settings” to quickly restore them, or click “Load Example” to view recommended parameters.
Start batch generation: After entering the “Generation Preview” page, click “Start Batch Generation”. The system will display the generation progress and statistical results.
Preview and export results: The results area displays the first 20 entries by default. Copying and downloading will process the complete results. Supports copying the current format, copying only UUIDs, and downloading TXT, CSV, and JSON files.
Batch validate UUIDs: Go to the “Validate Export” page and paste existing UUIDs to check standard format, compact format, URN format, version number, and variant information.

FAQ

A: UUID v4 is mainly random numbers and is suitable for general scenarios; UUID v7 includes time ordering, making it easy to sort; UUID v1 is suitable for compatibility with legacy time-based UUIDs; Mobile Device UUID uses the UUID v8 custom format and can combine brand, platform, region, and channel characteristics, making it suitable for mobile app testing.

A: The tool generates data using random data and standard UUID version rules, and provides a “deduplicate during generation” option. When enabled, it checks for duplicate values based on the final output format, making it suitable for preparing bulk test data.

A: No. Mobile device UUIDs are used to simulate test data and may include characteristics such as brand, platform, and region, but they do not represent real device hardware IDs and should not be used to impersonate real device identities.

A: Choose UUID v7 when test data needs to be sorted by generation time, when you want to easily observe indexing after writing to a database, or when API logs need to retain chronological characteristics.

A: TXT, CSV, and JSON export are supported. TXT is suitable for quick copying and viewing, CSV for processing in spreadsheet software, and JSON for API testing, script reading, or automated workflows.

A: To keep the page responsive, the preview area only displays the first 20 results. Actual copying and downloading will process the complete generated results, not just export the preview content.

A: It can recognize the standard hyphenated format, 32-character compact format, format with braces, and URN format, and displays the UUID version, variant, and format description.
