Which activity is primarily used to read data from a DataTable?

The primary activity used to read data from a DataTable is the Read Range activity. This activity is specifically designed to pull data from a specified range within a DataTable and store that data in a structured format that can be easily manipulated or accessed later in an automation workflow.

When a user employs the Read Range activity, they can define which specific rows and columns to read from the DataTable, whether it is a whole sheet or just particular sections, making it versatile for varying scenarios. This foundational operation is essential in RPA as it allows bots to gather the necessary data for processing, analysis, or decision-making tasks.

Other activities, such as Assign, Extract Data, and Get Row Item, serve different purposes. Assign is used for assigning values to variables, Extract Data refers to the process of gathering specific pieces of information from a larger dataset but does not inherently read a DataTable, and Get Row Item is utilized to retrieve a specific item from a designated row in an existing DataTable. Each of these activities plays a role in handling data but is not primarily designed for reading data from a DataTable in the same comprehensive way that Read Range does.
