Which UiPath activity would you use to create a custom structure for data?

The Build Data Table activity is designed for creating a custom structure for data in UiPath. This activity allows users to define the columns of the data table, including naming columns, setting data types, and specifying whether the columns can contain null values. Once the structure is established, you can add rows of data that conform to this structure, thereby having a well-defined data set to work with throughout your automation process.

This activity is particularly useful in scenarios where you need to gather and organize pieces of related information into a single entity, which can later be manipulated or utilized in various operations within the automation workflow. The flexibility of the Build Data Table activity makes it a foundational element in handling structured data effectively in RPA projects.

In contrast, the other activities listed serve different purposes. Add Data Row is used to insert a new row into an existing data table rather than to create its structure. The Merge DataTable activity combines two data tables, retaining the structure of the existing tables. The Filter Data Table activity is used for selecting specific rows from a data table that meet certain conditions, but it does not facilitate the creation or definition of a data structure.
