Not completely sure what you are trying to accomplish, but exporting data to a csv file can be done with the module you mentioned, but also with the export buttons that come standard with Mendix.
With the module you setup a configuration where you set the entity that holds the data that you want to export. Then select the columns that you want to export. Make sure the separator is a comma or when using excel use the semi colon as separator character.
To setup the module have a look at the documentation and at the example export that is provided in the module.
