UUID वैलिडेटर के बारे में
UUID सत्यापनकर्ता एक उपकरण है जो UUID/GUID पहचानकर्ताओं की वैधता और प्रारूप की जाँच करता है। यह UUID के सभी संस्करणों (v1-v5) का समर्थन करता है।
UUID वैलिडेटर की मुख्य विशेषताएं
- Validate any UUID or GUID against the RFC 4122 standard format
- Detect UUID version (v1, v3, v4, v5)
- Clear pass/fail result for each UUID validated
- Supports bulk validation — one UUID per line
- Accepts both uppercase and lowercase UUIDs
- Works entirely in-browser — no server requests
- Instant results with no submit delay
- Explains why an invalid UUID fails the check
उदाहरण
Validate a UUID v4 from an API response
Confirm that an ID returned by an API is a properly formatted UUID v4.

Invalid UUID — incorrect length (missing characters in last section)
सामान्य उपयोग के मामले
- Validating UUIDs in API request payloads before processing them
- Checking UUID format in database import files before bulk insertion
- Verifying UUID generation in unit tests and integration tests
- Debugging API errors caused by malformed UUID parameters
- Confirming that a GUID from a legacy Windows system is RFC 4122-compliant
- Batch-checking a list of UUIDs from a data export for format compliance
समस्या निवारण
UUID is rejected despite looking correct
समाधान
Check for invisible characters, extra whitespace, or missing hyphens. A valid UUID must have exactly 5 groups separated by hyphens in the pattern 8-4-4-4-12 characters.
UUID version is shown as unknown
समाधान
The version digit (the first character of the third group) must be 1–5. If the UUID was generated by a system using a non-standard method, it may not match any RFC 4122 version.
GUID from Windows appears invalid
समाधान
Windows GUIDs are sometimes wrapped in curly braces ({550e8400-...}). Remove the curly braces before validating — the UUID inside is the actual value.
अक्सर पूछे जाने वाले प्रश्न
What UUID versions are supported?
The validator detects UUID versions 1 (time-based), 3 (name-based MD5), 4 (random), and 5 (name-based SHA-1) in standard RFC 4122 hyphenated format.
What is the difference between a UUID and a GUID?
GUID (Globally Unique Identifier) is Microsoft's term for UUID. They refer to the same 128-bit identifier format. Both follow the same RFC 4122 standard and are interchangeable in practice.
What is UUID v4?
UUID v4 is randomly generated, making it the most common type for new applications. It provides 122 bits of randomness, making collisions astronomically unlikely without requiring coordination between systems.
Is UUID v4 truly unique?
With 2^122 possible values, the probability of two random UUIDs colliding is negligibly small for any practical application. You would need to generate billions of UUIDs per second for centuries to encounter a collision.
Can I validate UUIDs in bulk?
Yes. Paste one UUID per line and the tool validates all of them, showing pass/fail results for each entry.
What format does a valid UUID follow?
A valid UUID follows the pattern xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx, where x is a hexadecimal digit, M is the version digit (1–5), and N is the variant digit (8, 9, a, or b for RFC 4122).
Is my data sent to a server?
No. All validation is performed locally in your browser using a regular expression check against the RFC 4122 pattern. Your UUIDs are never transmitted or stored.
Does it validate UUID nil values?
The nil UUID (00000000-0000-0000-0000-000000000000) is technically a valid UUID format per RFC 4122. It is used as a placeholder or null equivalent in some systems.
