start_convert.py

Launcher that orchestrates conversions between Excel workbooks and prompt documents
using the following conventions:

Input locations (relative to repo root):
- ./prompt_excel/  # place .xlsx files here for Excel → Docs
- ./prompt_docs/   # place prompt folders here for Docs → Excel

Output locations (under repo root, named by source file/folder mtime):
- ./prompt_docs_YYYYMMDD_HHMMSS/  # Excel → Docs results (copies of prompts/*)
- ./prompt_excel_YYYYMMDD_HHMMSS/ # Docs → Excel results (rebuilt.xlsx)

Usage:
  # Auto mode: if there are .xlsx under prompt_excel, run Excel→Docs;
  # if there is a docs set under prompt_docs, run Docs→Excel.
  python prompt-library/scripts/start_convert.py

  # Force a mode:
  python prompt-library/scripts/start_convert.py --mode excel2docs
  python prompt-library/scripts/start_convert.py --mode docs2excel

Notes:
- No interactive prompts; behavior is driven by the file presence and CLI flags
- Requires pandas, openpyxl, PyYAML (see scripts/requirements.txt)
