+- **Kunden-Export**: Alle Kunden mit Lizenzstatistiken
+- **Format-Optionen**: Excel (.xlsx) und CSV (.csv)
+- **Deutsche Formatierung**: Datum als dd.mm.yyyy, Status auf Deutsch
+- **UTF-8 Export**: Korrekte Kodierung für Umlaute
+- **Export-Buttons**: Dropdown-Menüs in Lizenz- und Kundenübersicht
+
+**Geänderte Dateien:**
+- v2_adminpanel/app.py (export_licenses() und export_customers() Routen)
+- v2_adminpanel/requirements.txt (pandas und openpyxl hinzugefügt)
+- v2_adminpanel/templates/licenses.html (Export-Dropdown hinzugefügt)
+- v2_adminpanel/templates/customers.html (Export-Dropdown hinzugefügt)
+
+**Technische Details:**
+- Pandas für Datenverarbeitung
+- OpenPyXL für Excel-Export
+- CSV mit Semikolon-Trennung für deutsche Excel-Kompatibilität
+- Automatische Spaltenbreite in Excel
+- BOM für UTF-8 CSV (Excel-Kompatibilität)
