Which functionality does the data manager provide when loading customer data from a QVD file?

The data manager in Qlik Sense provides the capability of data profiling and field formatting when loading customer data from a QVD file. Data profiling involves analyzing the different fields within the dataset to gain insights into the quality and structure of the data, such as identifying data types, null values, or inconsistencies. This is essential for ensuring that the data being loaded is accurate and reliable.

Additionally, field formatting allows users to specify how the data should be presented within Qlik Sense. This includes defining numeric formats, date formats, or even applying string manipulations, helping users maintain consistency and clarity in their reports and visualizations. By having these functionalities, the data manager facilitates a smoother data loading process that leads to more effective analysis and visualization later on.

The other functionalities, such as data visualization capabilities, data export options, and data cleansing features, are not directly related to the data loading process from QVD files in the data manager context. Visualization pertains to how data is represented in charts or dashboards, export options deal with saving data in various file formats, and data cleansing involves removing or correcting errors in the data itself, which may occur at a different stage in the data processing workflow.
