+# Label mit LibreOffice aus Spreadsheet erstellen
+
+
+Folgender Use-Case wird dargestellt:
+* Benötigt werden Schilder für die Bilder bei einer Kunstausstellung
+* Die Schilder sollen möglichst platzsparend ausdruckbar sein
+* Daten liegen als Zeilen in einer Excel-Datei vor
+
+
+## 1. Excel-Datei in ods-Datei umwandeln
+
+Excel-Datei einfach in LibreOffice Calc öffnen
+und dann als .ods Speichern
+
+
+## 2. Datenbank aus ods-Datei erzeugen
+
+* LibreOffice Writer öffnen
+* File > Wizards > Address Data Source
+
+* Other external data source
+* Settings > Database type: Spreadsheet > ods Datei auswählen
+* "Tabelle", also Sheet auswählen
+* "Field Assignment" überspringen
+* "Data Source Title" = Name der Datenbank
+
+
+## 3. Label erstellen
+
+* LibreOffice Writer Instanz weiterverwenden
+* File > New > Labels
+
+### 3.1 Labels > Inscription
+
+* "Database", "Table" und "Database field" auswählen > Auf Pfeil nach links klicken um Felder ins Label zu schreiben
+* Das "Label text" Feld ist ein Freitext-Feld, kann also beliebig arrangiert werden
+
+### 3.2 Labels > Format
+
+Brand: "A-one"
+Type: Keine Ahnung welcher der "richtige" A4-Type ist, der erste taugt
+
+Auf "New Document" klicken
+
+
+## 4. PDF erzeugen
