Exporting a report allows the user to save the report data as a file that can be opened and edited in other applications, such as Microsoft Excel or Google Sheets. The user can choose to export the report as a formatted report, which preserves the report formatting and layout, or as a details only report, which includes only the report data without the formatting and layout.
