You can export any grid information directly into excel.
First, set the grid view so it contains the information and organization that you want. The excel export will contain the columns you have included in your view, in the order they are on the screen. The export will also preserve any grouping you have set on the view.
Then you can export the data by clicking on the EXCEL icon on the menu. Alternatively you can right click and select EXPORT.
This exported file will be in your download folder.
