What is the function of the load script in Qlik Sense?

The load script in Qlik Sense is primarily responsible for defining how data is loaded, transformed, and managed within the application. This script is a crucial part of the data preparation process, as it allows users to specify the data sources, perform data transformations, and control how the data is structured before it is visualized in the application.

When the load script runs, it extracts data from various sources—such as databases, spreadsheets, and other data files—then applies any necessary transformations, such as filtering, aggregating, or altering data formats. This ensures that the data loaded into Qlik Sense is accurate and ready for analysis.

By writing and modifying the load script, users have a high degree of control over the shape and quality of the data visualizations they create, making this function foundational to effective data analysis in Qlik Sense. In contrast, the other options describe functions not directly related to the load script: visualizations pertain to the representation of data, security protocols govern access controls, and user interface layout is concerned with how users interact with the application visually.
