Format-Referenz

Wichtige Filter

• writer_pdf_Export — Writer→PDF mit Kontrolle
• calc_pdf_Export — Calc→PDF
• impress_pdf_Export — Impress→PDF
• Text (encoded):UTF8 — UTF-8 Text-Export
• MS Word 2007 XML — docx (Writer)
• Calc MS Excel 2007 XML — xlsx (Calc)

Flags

• --headless — Kein GUI (impliziert bei --convert-to)
• --outdir \x3Cpath> — Ausgabeverzeichnis (sonst cwd)
• --infilter=\x3Cfilter> — Eingabe-Filter erzwingen (z.B. für CSV-Encoding)
• --convert-images-to \x3Cfmt> — Bilder im Dokument konvertieren
• -env:UserInstallation=file:///tmp/loprofile — Eigenes Profil nutzen

Beispiele

CSV → Excel mit korrektem Encoding

libreoffice --headless --infilter="Text - txt - csv (StarCalc):44,34,0,1,1" \
  --convert-to xlsx:"Calc MS Excel 2007 XML" daten.csv --outdir ./export/

Batch: Alle ODT → PDF

libreoffice --headless --convert-to pdf *.odt --outdir ./pdfs/

HTML mit Bildkonvertierung

libreoffice --headless --convert-to "html:XHTML Writer File:UTF8" \
  --convert-images-to "jpg" bericht.docx

Text aus PDF extrahieren

# 3. Extract text for search indexing
find "$PROCESSED_DIR" -name "*.pdf" | while read pdf; do
    ./scripts/libreoffice-extract.sh "$pdf" --output "${pdf%.pdf}.txt" --clean
done

# 4. Create combined index
./scripts/libreoffice-merge.sh "$PROCESSED_DIR"/*.pdf --output "$PROCESSED_DIR/index.pdf" --toc

Tipps

• Java-Warnungen (javaldx) können ignoriert werden — Grundfunktionen gehen ohne Java
• Für parallele Konvertierungen: eigene Profile nutzen (-env:UserInstallation=...)
• CSV: --infilter nutzen um Trennzeichen/Encoding zu setzen
• Bei Fehlern: Dateiname ohne Leerzeichen/Sonderzeichen testen
• Use the reference documentation for advanced filter options and JSON configuration
• Check examples.md for complete automation workflows and integration patterns
