Scripting is a very powerful feature in QlikView, which enables the control of the data load options and data transformations. It enables the use of many inbuilt functions available in QlikView and creates subroutines to be used across multiple scripts within a QlikViewdocument.
Scripting is done using the Script Editor. It is accessed from the File menu using Script Editor. We can also press Control +E to open the script editor window. It prepopulates some data formats that are set as default formats for the data to be processed. For example, the Thousand separator is a comma and date is in Month-day-year format. These can be changed to suit the incoming data as per the need.
