.. _auto_keyvalue_extract_values:

*EXTRACT THE VALUES*
====================

Extracts the individual values from a key-value pair object and exposes each value as a scalar output. Use this worker when you need to unpack a key-value store and pass its values downstream in a workflow.

When to use
-----------

Classification: **process**.

Tagged: ``extract``, ``keyvalue``, ``scalar``, ``transform``, ``unpack``.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Kv1
     - kv1
     - keyvalue
     - —
     - 
     - The key-value pair object whose values are to be extracted; accepts any key-value input (optional — leave empty if the pair is not yet available and will be wired at runtime).

Outputs
-------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20

   * - Label
     - ID
     - Type
     - Description
   * - keyvalue_extract_output_1
     - keyvalue_extract_output_1
     - scalar
     - A scalar holding the extracted value from the corresponding key in the input key-value pair; one output port is generated per key resolved at runtime.
