# Office to Markdown Converter Skill (v2) ## Description Convert office documents (PDF, DOC, DOCX, PPTX) to Markdown format. This skill uses the word-extractor library for .doc support and provides full OpenClaw integration. ## When to Use - When you need to extract text from office documents - When you want to convert documents to readable Markdown format - When analyzing document content in OpenClaw - Specifically when dealing with legacy .doc format files ## Supported Formats - **PDF (.pdf)**: Text extraction using pdf-parse - **Word (.docx)**: Formatting preservation using mammoth + turndown - **Legacy Word (.doc)**: Text extraction using word-extractor (supports Chinese encoding) - **PowerPoint (.pptx)**: Basic text extraction using python-pptx ## Dependencies - Node.js with npm packages: pdf-parse, mammoth, turndown, word-extractor - Python3 with python-pptx (for PPTX conversion, optional) - OpenClaw exec tool permission ## Installation ### 1. Copy the skill to your workspace: ```bash cp -r /root/.openclaw/workspace/office-to-md-v2/office-to-md /path/to/your/workspace/ ``` ### 2. Install dependencies: ```bash cd /path/to/your/workspace/office-to-md npm install ``` ### 3. For PPTX support (optional): ```bash pip3 install python-pptx ``` ## Usage in OpenClaw ### Method 1: Direct exec call ```javascript // Convert any supported document const result = await exec( 'node /path/to/office-to-md/openclaw-skill.js /path/to/document.doc', { workdir: '/path/to/workspace', timeout: 60000 } ); if (result.exitCode === 0) { console.log('✅ Document converted successfully'); // Output file: /path/to/document.md } else { console.error('❌ Conversion failed:', result.stderr); } ``` ### Method 2: Using the wrapper function ```javascript // Import the converter const { convertOfficeToMarkdown } = require('/path/to/office-to-md/openclaw-skill.js'); // Convert document const conversionResult = await convertOfficeToMarkdown('/path/to/document.pdf'); if (conversionResult.success) { console.log(`Output: ${conversionResult.outputPath}`); console.log(`Preview: ${conversionResult.preview}`); } else { console.error(`Error: ${conversionResult.error}`); } ``` ### Method 3: Complete OpenClaw integration function ```javascript async function convertDocumentToMarkdown(filePath) { // Validate file exists try { await read(filePath); } catch (error) { return { success: false, error: `File not found: ${filePath}` }; } // Check file extension const ext = filePath.toLowerCase().slice(-5); const supported = ['.pdf', '.doc', '.docx', '.pptx']; if (!supported.some(s => ext.endsWith(s))) { return { success: false, error: `Unsupported file type. Supported: ${supported.join(', ')}` }; } // Convert using the skill const cmd = `node /path/to/office-to-md/openclaw-skill.js "${filePath}"`; const result = await exec(cmd, { workdir: '/path/to/workspace', timeout: 120000 // 2 minutes for large files }); if (result.exitCode === 0) { const outputPath = filePath.replace(/\.[^/.]+$/, '.md'); return { success: true, outputPath: outputPath, message: `Converted to: ${outputPath}` }; } else { return { success: false, error: result.stderr || 'Conversion failed' }; } } // Usage example const result = await convertDocumentToMarkdown('/path/to/document.doc'); if (result.success) { const markdown = await read(result.outputPath); console.log(markdown.substring(0, 1000)); } ``` ## Examples ### Example 1: Convert and analyze a document ```javascript // Convert a .doc file and analyze its content const docPath = '/path/to/document.doc'; const convertResult = await exec( `node /path/to/office-to-md/openclaw-skill.js "${docPath}"`, { workdir: '/path/to/workspace' } ); if (convertResult.exitCode === 0) { const mdPath = docPath.replace('.doc', '.md'); const content = await read(mdPath); // Analyze the content const wordCount = content.split(/\s+/).length; const lines = content.split('\n').length; const hasChinese = /[\u4e00-\u9fff]/.test(content); console.log(`Document analysis:`); console.log(`- Word count: ${wordCount}`); console.log(`- Lines: ${lines}`); console.log(`- Contains Chinese: ${hasChinese}`); console.log(`- Preview: ${content.substring(0, 200)}...`); } ``` ### Example 2: Batch conversion ```javascript // Convert multiple documents of different formats const documents = [ '/path/to/report.pdf', '/path/to/legacy.doc', '/path/to/modern.docx', '/path/to/presentation.pptx' ]; const results = []; for (const doc of documents) { console.log(`Converting ${doc}...`); const result = await exec( `node /path/to/office-to-md/openclaw-skill.js "${doc}"`, { workdir: '/path/to/workspace', timeout: 90000 } ); const success = result.exitCode === 0; results.push({ file: doc, success: success, error: success ? null : result.stderr }); console.log(success ? '✅ Success' : '❌ Failed'); } // Summary const successful = results.filter(r => r.success).length; console.log(`\nConversion summary: ${successful}/${results.length} successful`); ``` ## API Reference ### convertOfficeToMarkdown(filePath) Returns a Promise that resolves to: ```javascript { success: boolean, outputPath?: string, markdown?: string, preview?: string, fileType?: string, message?: string, stats?: { lines: number, characters: number, words: number }, error?: string, stack?: string } ``` ## Configuration ### Timeout Settings - Small files (<1MB): 30 seconds - Medium files (1-10MB): 60 seconds - Large files (>10MB): 120 seconds ### Memory Limits - Default Node.js memory limit is sufficient for most documents - For very large files, you may need to increase memory: ```bash node --max-old-space-size=4096 openclaw-skill.js large-file.doc ``` ## Troubleshooting ### Common Issues 1. **"File not found"** - Check file path and permissions - Use absolute paths for reliability 2. **"Unsupported file type"** - Ensure file has correct extension - Check if file is actually the claimed format 3. **Conversion errors with .doc files** - The file may be corrupted or in an unusual format - Try opening in Word and saving as .docx first 4. **Chinese text appears as gibberish** - word-extractor should handle Chinese encoding automatically - If issues persist, the file may use unusual encoding 5. **Timeout errors** - Increase timeout for large files - Check system resources ### Debug Mode Enable debug logging by setting environment variable: ```bash DEBUG=office-to-md node openclaw-skill.js document.doc ``` ## Performance - PDF: Fast, depends on file size - DOCX: Fast to medium, good formatting preservation - DOC: Medium, requires binary parsing - PPTX: Slow, requires Python and external library ## Limitations - Images in documents are not extracted - Complex formatting may not be fully preserved - Tables may convert imperfectly to Markdown - Very old or corrupted .doc files may fail - Password-protected files are not supported ## Changelog ### v2.0.0 (2026-02-15) - Added full .doc support using word-extractor - Fixed ESM compatibility issues with pptConverter - Added comprehensive OpenClaw integration - Improved Chinese text extraction - Added structured output with statistics ### v1.0.0 (Initial) - Basic PDF, DOCX, PPTX support - Simple conversion without .doc support ## License This skill is provided as-is. The underlying libraries have their own licenses: - pdf-parse: MIT - mammoth: BSD-2-Clause - turndown: MIT - word-extractor: MIT - python-pptx: MIT

### API Reference

#### convertOfficeToMarkdown(filePath)
```javascript
// Returns:
{
  success: boolean,
  outputPath?: string,
  markdown?: string,
  preview?: string,
  fileType?: string,
  message?: string,
  stats?: {
    lines: number,
    characters: number,
    words: number
  },
  error?: string,
  stack?: string
}
```

### Examples
See the `examples/` directory for complete usage examples:
- Basic conversion
- Error handling
- Batch processing
- Direct module usage

## Performance
- **Small files** (<1MB): < 10 seconds
- **Medium files** (1-10MB): 10-30 seconds
- **Large files** (>10MB): 30-120 seconds
- **Memory usage**: Typically < 100MB

## Troubleshooting

### Common Issues

**Q: .doc files show gibberish instead of Chinese text**
A: The word-extractor library should handle Chinese automatically. If issues persist, the file may be corrupted.

**Q: Conversion times out**
A: Increase the timeout for large files: `timeout: 120000` (2 minutes)

**Q: "Unsupported file type" error**
A: Check file extension and ensure it's one of: .pdf, .doc, .docx, .pptx

**Q: PPTX conversion fails**
A: Install python-pptx: `pip3 install python-pptx`

### Debug Mode
```bash
DEBUG=office-to-md node openclaw-skill.js document.doc
```
