+### Export-Funktionen Analyse und Lösungsplan ✅
+
+**Problem:**
+- CSV Export Buttons vorhanden, aber Backend liefert immer Excel-Dateien
+- Monitoring Export zeigt nur Platzhalter-Alerts ("Export-Funktion wird implementiert")
+- Leads/CRM Module hat keine Export-Funktionalität
+- Format-Parameter wird in Export-Routes ignoriert
+
+**Analyse-Ergebnisse:**
+1. Excel-Exporte funktionieren für: Lizenzen, Kunden, Sessions, Audit Logs, Ressourcen
+2. Export-Routes in `export_routes.py` prüfen nie den `format=csv` Parameter
+3. Nur `create_excel_export()` existiert, keine CSV-Generierung implementiert
+4. Monitoring-Exporte haben nur JavaScript-Platzhalter ohne Backend
+5. Lead Management hat keine Export-Funktionalität
+
+**Lösungsplan (YAGNI & Strukturiert):**
+
+1. **CSV Export Fix (Priorität 1)**
+   - Format-Parameter in bestehenden Export-Routes prüfen
+   - CSV als Alternative zu Excel hinzufügen (Excel bleibt Default)
+   - Python's eingebautes csv-Modul nutzen, keine neuen Dependencies
+   - Minimale Änderung: ~10 Zeilen pro Route
+
+2. **Monitoring Export (Priorität 2)**
+   - Neue Route `/export/monitoring` nach bestehendem Muster
+   - Daten von existierenden Monitoring-Endpoints nutzen
+   - Excel und CSV Format unterstützen
+
+3. **Lead Export (Priorität 3)**
+   - Route `/leads/export` zum Lead Blueprint hinzufügen
+   - Institutionen mit Kontakt-Anzahl exportieren
+   - Gleiches Muster wie andere Exporte verwenden
+
+**Vorteile dieser Lösung:**
+- Keine Refaktorierung nötig
+- Bestehende Excel-Exporte bleiben unverändert
+- Konsistentes URL-Muster mit format-Parameter
+- Rückwärtskompatibel (Excel als Standard)
+- Einfach erweiterbar für zukünftige Formate
+
+**Implementierung abgeschlossen:**
+
+1. **CSV Export Support hinzugefügt:**
+   - Neue Funktion `create_csv_export()` in `utils/export.py`
+   - Alle Export-Routes prüfen jetzt den `format` Parameter
+   - CSV-Dateien mit UTF-8 BOM für Excel-Kompatibilität
+
+2. **Monitoring Export implementiert:**
+   - Neue Route `/export/monitoring` in `export_routes.py`
+   - Exportiert Heartbeats und optional Anomalien
+   - JavaScript-Funktionen in Templates aktualisiert
+
+3. **Lead Export hinzugefügt:**
+   - Neue Route `/leads/export` in `leads/routes.py`
+   - Exportiert Institutionen mit Kontakt-Statistiken
+   - Export-Buttons zu Institutions-Template hinzugefügt
+
+**Geänderte Dateien:**
+- `utils/export.py` - CSV-Export-Funktion hinzugefügt
+- `routes/export_routes.py` - Format-Parameter-Prüfung für alle Routes
+- `routes/export_routes.py` - Monitoring-Export hinzugefügt
+- `leads/routes.py` - Lead-Export-Route hinzugefügt
+- `templates/monitoring/analytics.html` - Export-Funktionen aktualisiert
+- `templates/monitoring/live_dashboard.html` - Export-Funktionen aktualisiert
+- `leads/templates/leads/institutions.html` - Export-Buttons hinzugefügt
+
+**Testing abgeschlossen:**
+- Alle Export-Routes sind verfügbar und funktionieren
+- CSV-Export generiert korrekte CSV-Dateien mit UTF-8 BOM
+- Excel bleibt der Standard wenn kein format-Parameter angegeben
+- Container wurde neu gebaut und deployed
+- Alle 7 Export-Endpoints unterstützen beide Formate:
+  - `/export/licenses`
+  - `/export/customers`
+  - `/export/sessions`
+  - `/export/audit`
+  - `/export/resources`
+  - `/export/monitoring`
+  - `/leads/export`

+
+### Lizenzfilter System komplett überarbeitet ✅
+
+**Problem:**
+- Checkbox-basiertes Filtersystem war unübersichtlich und fummelig
+- "Fake-Daten anzeigen" Checkbox funktionierte nicht richtig
+- "Läuft bald ab" Status machte keinen Sinn (inaktive Lizenzen können nicht ablaufen)
+
+**Lösung 1 - Neues Dropdown-System:**
+- Checkbox-Filter ersetzt durch 3 klare Dropdowns:
+  - Datenquelle: Echte Lizenzen / 🧪 Fake-Daten / Alle Daten
+  - Lizenztyp: Alle Typen / Vollversion / Testversion
+  - Status: Alle Status / ✅ Aktiv / ⚠️ Abgelaufen / ❌ Deaktiviert
+- Auto-Submit bei Änderung
+- Übersichtlicher "Filter zurücksetzen" Button
+
+**Lösung 2 - API Bug Fix:**
+- SQLAlchemy Fehler behoben: `text()` Wrapper für Raw SQL Queries hinzugefügt
+- License Server API funktioniert jetzt korrekt
+
+**Lösung 3 - Status-Logik korrigiert:**
+- "Läuft bald ab" komplett entfernt (gehört nur ins Dashboard als Hinweis)
+- Klare Trennung der 3 Status:
+  - Aktiv = `is_active=true` (egal ob abgelaufen)
+  - Abgelaufen = `valid_until <= heute` (läuft aber weiter bis manuell deaktiviert)
+  - Deaktiviert = `is_active=false` (manuell gestoppt)
+- Lizenzen laufen nach Ablauf weiter bis zur manuellen Deaktivierung
+
+**Geänderte Dateien:**
+- `templates/licenses.html` - Komplettes Filter-UI überarbeitet
+- `routes/license_routes.py` - Filter-Logik angepasst
+- `v2_lizenzserver/app/core/api_key_auth.py` - SQL Bug behoben
