# Creating NULL values from text files

It is possible to define a symbol, which when it occurs in a text file or an inline clause will be interpreted as a real NULL value. Use the following statement:

[](https://help.qlik.com/en-US/qlikview/Subsystems/Client/Content/QV_QlikView/Scripting/create-null-values-from-text-files.htm)SET NULLINTERPRET=<sym>;

The symbol <sym> is to be interpreted as NULL. <sym> may be any string.

In order to reset this functionality to the default interpretation, use:

SET NULLINTERPRET=;

Information note The use of NULLINTERPRET only affects data from text files and inline clauses.
