📄 Documents

Input	Output	Engine chain
TXT	PDF	ReportLab → pypandoc (if Pandoc installed)
TXT	DOCX	Word COM → pypandoc → python-docx native
RTF	PDF	ReportLab native (full fidelity, no Office needed)
RTF	DOCX	Word COM → pypandoc → striprtf + python-docx
CSV	JSON	Native
JSON	CSV	Native
XLSX	PDF	Microsoft Excel COM → LibreOffice CLI → ReportLab (auto portrait/landscape, multi-sheet)
XLSX	JSON	openpyxl native
XLSX	CSV	openpyxl native
PPTX	PDF	Microsoft PowerPoint COM → LibreOffice CLI → python-pptx + ReportLab + Matplotlib
HTML	PDF	pdfkit (wkhtmltopdf) → WeasyPrint → ReportLab
PDF	HTML	PyMuPDF dict-mode (flow layout, base64-embedded images)
EPUB	PDF	pypandoc → spine-order native (images embedded)

PDF → DOCX has its own dedicated pipeline: pdf2docx (layout-preserving) → text-only fallback → image+text hybrid. Quality depends on the source PDF — scanned PDFs without an embedded text layer are only partially recoverable.

.ppt (legacy binary format): requires Microsoft Office or LibreOffice. python-pptx cannot open old .ppt files natively.
