GUID Generator (Apify Actor)

The GUID Generator Actor automatically creates globally unique identifiers (GUIDs) in bulk for workflows that need fast, reliable unique strings at scale.

Features

• Bulk generation: Generate thousands of identifiers per run.
• Multiple types:
  • UUID v1, v4, v5
  • Custom alphanumeric identifiers (custom charset + length)
  • Sequential identifiers (optionally timestamp-prefixed)
• Customizable patterns: Prefix/suffix support for all types, UUIDv5 name templating.
• Uniqueness validation: Optional in-run duplicate detection.
• Apify output: Always outputs to the default Apify dataset as JSON items: { "guid": "..." }

Running on Apify

To run this Actor on the Apify platform, create a new task and set the desired input configuration. The generated GUIDs will be saved to the Actor's default dataset.

Input

The input for this Actor should be a JSON object with the following properties:

• count (number): Number of identifiers to generate (default: 5).
• type (string): One of v1, v4, v5, alphanumeric, sequential (default: v4).
• prefix (string): Optional prefix.
• suffix (string): Optional suffix.
• validateUnique (boolean): Ensure no duplicates are produced (default: true).
• batchSize (number): Dataset push batch size (default: 5000).

UUIDv5 options (required when type: "v5"):

• uuidV5Name (string)
• uuidV5Namespace (string): DNS, URL, or a UUID string
• uuidV5NameTemplate (string): supports {{name}}, {{index}} (1-based), {{index0}} (0-based)

Alphanumeric options (used when type: "alphanumeric"):

• alphanumericLength (number, default: 16)
• alphanumericCharset (string, default: base62)

Sequential options (used when type: "sequential"):

• sequentialStart (number, default: 1)
• sequentialStep (number, default: 1, must not be 0)
• sequentialPadding (number, default: 6)
• sequentialTimestampPrefix (boolean, default: true)
• sequentialTimestampUnit (string, default: ms, one of ms/s)
• sequentialDelimiter (string, default: -)

Output

The output is a list of JSON objects, where each object has a guid property containing the generated GUID.

Example Output:

[
  {
    "guid": "a17e8844-f7e1-4bd1-913c-f68bb4a1ad4b"
  },
  {
    "guid": "e570fc03-65f4-4269-ad4f-5c34ca151146"
  }
]
