Office Document Extractor

Zero-dependency converter for Microsoft Office documents. Extracts text and structure from DOCX, XLSX, and PPTX files into clean Markdown.

Quick Start

# Single file
python3 scripts/main.py report.docx -o report.md

# Batch convert a directory
python3 scripts/main.py ./documents --batch -o ./markdown

Supported Formats

How It Works

• DOCX: Parses the ZIP archive's XML directly using Python's zipfile and xml.etree
• XLSX: Uses bundled openpyxl (pure Python, no C extensions)
• PPTX: Parses the ZIP archive's slide XML directly

No external commands, no network calls, no pip install required.

Usage

Single File

python3 scripts/main.py <input_file> [-o <output.md>]

Auto-detects format from file extension. If -o is omitted, outputs to .md.

Batch Conversion

python3 scripts/main.py <input_directory> --batch [-o <output_directory>]

Converts all .docx, .xlsx, .pptx files in the directory. Results saved to markdown_output/ by default.

Resources

scripts/

• main.py — Unified CLI for single-file and batch conversion
• docx_extractor.py — DOCX → Markdown (standard library only)
• xlsx_extractor.py — XLSX → Markdown tables (bundled openpyxl)
• pptx_extractor.py — PPTX → Markdown (standard library only)

Bundled Dependencies

• openpyxl/ — Pure Python Excel library (v3.1.5)
• et_xmlfile/ — openpyxl dependency (pure Python)

Limitations

• Does not extract images or embedded objects (text only)
• Does not preserve complex formatting (colors, fonts, layouts)
• Does not handle encrypted/password-protected files
• No OCR for scanned documents (use OpenClaw's native pdf tool for that)

Why This Skill?

Existing markitdown-based skills require pip install or external CLI tools, which triggers ClawHub security warnings. This skill is 100% self-contained — install it and use it immediately, even offline.
