The tabular overviews in BriefBuilder (which can be found in the navigation menu under ‘overviews’) can all be exported to Excel.
In each of the overviews, you can a small icon, right next to the overview’s name. If you click on that icon, you will get an Excel download of that particular overview.
Depending on the size of the overview, it may take some time to download the file. You can find the file in the download folder of your device.
