Four rules that explain most results

  • Workbooks and presentations are edited one part at a time. replace_text and extract_html take worksheet or slide (default 1); save_from_html splices the part back with sourceFile.
  • PPTX and email need the original to save. HTML alone becomes DOCX, XLSX, PDF, TXT, Markdown or EPUB; a presentation or a message needs sourceFile.
  • PDF is converted, not patched. It becomes flowing HTML; save the edit as DOCX when fidelity matters — turn a PDF into Word.
  • Form fields are Word only. get_form_fields reads DOCX, DOC, DOCM, DOT, DOTX, RTF and ODT.
