A variable in Qlik Sense is a container storing a static value or a calculation, for example a numeric or alphanumeric value. When you use the variable in the app, any change made to the variable is applied everywhere the variable is used. You can define variables in the variables overview, or in the script using the data load editor. You set the value of a variable using Let or Set statements in the data load script.
For more information, see Using variables in expressions and Working with variables in the data load editor.
You open the Variables overview by clicking 
in the edit bar when editing a sheet.
The variables overview lists all the variables that you can use in expressions. Expressions are used for making calculations based on the data in the app. When used, the variable is substituted by its value. Variables are case sensitive.
