**Example**

In this example, we will be manipulating an existing dataset by adding an empty column between fields, using the *GetLineFeed* Function Transformation object.

Our data is stored in a *Fixed Length File Source* object, and look like this:

Now, we will map source fields and the output value of the function transformation object to a *Delimited File Destination*.

Upon previewing the destination output, you can see that Astera Data Stack has added a new *value* column, thus a new empty string field for each record present, using the *GetLineFeed* function transformation object.
