Select Columns

The Select Columns Step is used to streamline a dataset by removing unused or irrelevant columns.

Key Features

  1. Remove Unnecessary Columns: Eliminate columns that are not required for further processing, reducing clutter.
  2. Improve Dataset Focus: Retain only the columns essential for analysis, reporting, or transformations.
  3. Optimize Performance: Minimize data size and complexity by excluding extraneous fields.

How to Use

  • Select Columns to Keep: Choose the columns that need to remain in the data block.
  • Remove Unused Columns: Deselect or exclude columns that are not needed.

This step ensures a cleaner and more manageable dataset, making subsequent steps more efficient and focused.
