Delete Columns

Overview

The DeleteColumns component removes specific columns from a CSV file. It allows users to define which columns to delete, using either column names (if headers exist) or column indices.

Usage

Instructions

1. Determine Column Identification Method

   • Ensure the correct format is used for column identification.

3. Processing

   • The component removes the selected columns and generates a new CSV file.
