Rename columns

Description

The Rename Columns activity allows you to change column names in a dataset using a user-defined mapping of existing column names to new ones. This is especially useful when working with data from diverse sources that use inconsistent or undescriptive column headers.

By renaming columns, you can make your data easier to understand, standardize naming conventions, or prepare it for integration with other systems or tools.

Use this activity to:

• Standardize inconsistent column names from different sources
• Improve readability before presenting data
• Align column headers with naming conventions expected by downstream activities

Use case: If a dataset from an external vendor uses cryptic field names like col1, col2, etc., this activity can rename them to Product, Category, and Price for clarity and consistency.
