In all overview screens, such as those for relations, the export function works the same way.
There are two buttons in the top right corner: 'Download PDF' and 'Download Excel'. These buttons allow you to download the current data displayed on the screen.
Below is a list of items that can be exported in this way.
Relations
All overviews under:
Overviews
Customer overviews
Supplier overviews
General
Products
Invoices can also be exported. To export invoices, select the invoice or invoices you wish to download, then choose 'Download' under Select action.
It may happen that your browser blocks the download via the popup blocker. If this occurs, allow the download to obtain the file.
