.. _auto_dataset_to_keyvalue:

*DATASET TO KEYVALUE*
=====================

Converts a tabular dataset into a key-value store, mapping column names to their corresponding values. Use this worker when downstream nodes expect a key-value structure rather than a full dataset table.

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

Classification: **process**.

Tagged: ``conversion``, ``dataset``, ``keyvalue``, ``transform``.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Choose Dataset
     - dataset_1
     - dataset
     - —
     - 
     - The input dataset (tabular) to be converted into key-value pairs; leave unset if the dataset will be wired in dynamically at runtime.

Outputs
-------

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

   * - Label
     - ID
     - Type
     - Description
   * - dataset_to_keyvalue_output_1
     - dataset_to_keyvalue_output_1
     - keyvalue
     - The resulting key-value store produced from the input dataset, where each column name becomes a key mapped to its corresponding cell value.
