xlsx2pdf.py

Convert Excel workbooks to PDF on Linux — one sheet per page, landscape, with a labeled watermark.

What it does

• Sets every sheet to landscape orientation, fit to one page (width × height)
• Exports to PDF via LibreOffice headless
• Overlays each page with a semi-transparent watermark showing the sheet name

Fix

Latest versions of Windows WebDav in Explorer uses Digest Authorization only, but Apache with LDAP supports only Basic Auth.

To enable back support of Basic Authorization we should enable WebClient service (set automatic in services.msc) and allow Basic Auth using regedit for WebClient

Enable WebClient
