There are only two mandatory steps to generate your data file: structure specification and output file selection.
To specify file structure the user should add a few column descriptions or import it from another file.
The most important column property is a generator, i.e. the fill out method for the field. The user should select it from menu and change options, if necessary.
Output file name can be selected with "..." button at the bottom panel of the main window. $DATE$ and $TIME$ macros can be used as a part of the file name.
