Valida GUIDs online per gratuito. Controlla GUID formato, versione, variante, length, normalized value e special GUID values instantly.
Review the format, version, variant and normalized GUID.
A Validatore GUID checks whether a GUID o UUID is correctly formed e identifies important informatoion such as its versione, variante e formato. This is useful quando working con APIs, database, Microsoft .NET applicazioni, distributed systems e applicazione identifiers.
A standard GUID is normally represented as 36 characters including four hyphens in an 8-4-4-4-12 pattern.
550e8400-e29b-41d4-a716-446655440000GUIDs e UUIDs use a versione field to identify how the identifier was generato. Questo validatore detects supported UUID versiones including v1, v3, v4, v5, v6, v7 e v8.
The variante identifies the UUID layout used by the identifier. For the standard RFC UUID variante, the variante field normally begins con 8, 9, A o B.
The Nil GUID contiene all zeros:
00000000-0000-0000-0000-000000000000A Nil GUID è un valid special value e is not automatically treatedas an invalid GUID.
GUID validation is useful before storing identifiers in database, processing API requests o passing identifiers between services. A formato-valid GUID does not necessarily mean that the identifier exists in your database o belongs to a particular user o resource.
A GUID validator focuses on whether the value follows GUID e UUID formatoting rules. A GUID checker can be utilizzato per additional checks depending on the applicazione, such as checking a value against another identifier o data source.
A Validatore GUID checks whether a GUID o UUID follows the expected formato e analyzes details such as its versione, variante, formato e normalized value.
Enter one o more GUIDs in the validator e click Valida GUIDs. Lo strumento checks each value e displays whether it is valid o invalid along con detailed informatoion.
Sì. Puoi enter multiple GUIDs, con one GUID per line, e validate them together.
Il validatore supporta standard 8-4-4-4-12 GUIDs, uppercase e lowercase values, braces, parentheses, URN formato e 32-character hexadecimal GUIDs senza hyphens.
Sì. Il validatore can identify UUID versiones including versione 1, 3, 4, 5, 6, 7 e 8 quando the versione informatoion is present in the identifier.
GUID e UUID generally refer to the same type of 128-bit identifier. GUID is commonly used in Microsoft e .NET environments, while UUID is the broader standards-based term.
The Nil UUID è un defined special UUID value consisting entirely of zeros. It should be treated as a special value rather than an ordinary generato UUID.
Il validatore is designed to perform validation in your browser. Your GUID values do not need to be uploaded to a server per the validation process.
