If you want to use a form for the export, click on the Form tab, located at the top of the Export dialog box.
You can then choose a form from the list of forms for the selected table. The main advantage of using a form is that the form method and the object methods associated with fields and variables are executed when each record is exported. This allows you to process the data during the export. Do not place buttons on the form. Subform objects are ignored.
Note: Fields and variables will be exported in the order specified by the entry order of the form.
