# GuidBench

> Free GUID and UUID generator with v4, v7, ULID, Nano ID, bulk JSON, SQL and C# exports, Base64 encoding and a private UUID inspector.

Generate UUID v4, UUID v7, ULID and Nano ID batches of up to 10,000. UUID v7 uses fresh randomness per ID by default, with an optional sequential mode. Copy or download one value per line, a JSON array, a SQL IN list or a C# string array. Format UUIDs with hyphens, uppercase, braces, Base64, Base64url or URL encoding. Inspect up to 1,000 UUIDs for recognised structure, variant, version, repeated values and an embedded v7 timestamp.
