Your supervisor wants Word, your paper is in LaTeX. Upload the .tex file and download a .docx — equations become native Word math, headings and lists survive intact.
Conversion runs on pandoc — the same engine behind countless academic workflows. Text, sectioning, lists, tables, inline and display math all convert; equations arrive as native Word equations (editable in Word's equation editor, not images). What doesn't translate: custom macros beyond standard packages, intricate float placement, and journal-class-specific layout — Word simply has no equivalent, so expect to re-polish layout there. For a thesis chapter or a paper draft to share with a Word-bound co-author, it's the fastest honest path.
