.. _auto_dataset_combine_scalars:

*COMBINE SCALARS*
=================

Collects one or more scalar values and assembles them into a single dataset (table), using configurable delimiters for headers and rows. Use this worker when you need to package loose scalar results — e.g. KPIs extracted from simulation responses — into a structured tabular output for downstream processing or reporting.

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

Classification: **process**.

Tagged: ``assembly``, ``combine``, ``dataset``, ``kpi``, ``merge``, ``scalars``, ``tabular``.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Headers
     - headers
     - scalar
     - —
     - 
     - Optional delimited string of column header names to assign to the output dataset; leave blank to use default or positional headers.
   * - Header Delimiter
     - header_delimiter
     - list
     - space
     - 
     - Delimiter used to split the Headers string into individual column names; choose from Space (default), Comma, Tab, or Equal.
   * - Row Delimiter
     - row_delimiter
     - scalar
     - space
     - 
     - Delimiter used to split each scalar value string into individual row cells; choose from Space (default), Comma, Tab, or Equal.
   * - Response To Extract From
     - responsetoextractfrom
     - scalar
     - —
     - 
     - One or more repeating scalar values (e.g. simulation response KPIs) to be combined into rows of the output dataset; supply at least one scalar for meaningful output.
