 **Export as spreadsheet (CSV)**, the spreadsheet icon after **View options**, downloads the bookings as a CSV file. It holds exactly what the tab shows: the search and the filters apply, and the rows follow **Sort by** from the view options (the grouping is left out, one row per booking). The columns are **Type**, **Title**, **Status**, **Start**, **End**, **From**, **To**, **Location**, **Confirmation** and **Notes**; **From** and **To** are filled for bookings with a route.
