ETL engine

Qlik Sense includes a built-in ETL engine that allows us to connect to many different sources, such as Excel, SQL, and Hadoop, to extract data into Qlik Sense. We can also use this ETL engine to transform the data, to manipulate the data, to clean up dirty data, or to create new data.

This is a very powerful component of the Qlik platform because we don't have to leave Qlik to do mappings, create buckets, or fix bad data; we can do everything we need right inside Qlik Sense, and there is even an intuitive user interface that guides users with no programming knowledge required.
