.. _auto_keyvalue_get_names:

*RETURN THE NAMES OF THE KEYVALUE ITEMS*
========================================

Extracts and returns the key names from a key-value input as a single delimited string. Use this worker when you need to enumerate the keys of a key-value collection for downstream processing or display.

Classification: **process**.

Inputs

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Response
     - response
     - keyvalue
     - —
     - 
     - The key-value collection whose key names are to be extracted; accepts any key-value input object as defined in the d3VIEW workflow glossary.
   * - De-Limiter
     - delimiter
     - scalar
     - ,
     - 
     - Character used to join the extracted key names into a single output string; defaults to a comma (',') — change only if downstream consumers expect a different separator (e.g. '/' or ';').

Outputs

   :widths: 20 20 20 20

   * - Label

     - Type
     - Description
   * - keyvalue_get_names_output_1
     - keyvalue_get_names_output_1
     - scalar
     - A single delimited string containing all key names found in the input key-value collection, joined by the specified delimiter (e.g. 'key1,key2,key3').
