## Conversion Guidelines

### Best Practices
1. **Check source PDF type**:
   - Native PDF (from Word/etc): Best results
   - Scanned PDF: Use OCR first
   - Image-based: Limited accuracy

2. **Formatting considerations**:
   - Complex layouts may shift
   - Fonts substitute if not installed
   - Tables may need adjustment
   - Headers/footers require review

### Quality Settings
| Setting | Result |
|---------|--------|
| **Exact** | Matches layout precisely, harder to edit |
| **Editable** | Optimized for editing, may shift layout |
| **Text only** | Plain text, no formatting |

### Common Issues
| Issue | Solution |
|-------|----------|
| Text as image | Run OCR before converting |
| Missing fonts | Embed or substitute fonts |
| Broken tables | Manually adjust in Word |
| Lost colors | Check color profile settings |
```

### PDF to Excel

### Ideal Sources
- PDF with clear table structure
- Financial statements
- Data reports
- Invoices with line items

### Extraction Methods
| Method | Use When |
|--------|----------|
| **Auto-detect tables** | Clear table borders |
| **Select area** | Tables without borders |
| **Full page** | Entire page is data |

### Quality Tips
1. Ensure PDF has selectable text (not scanned)
2. Clean table borders help detection
3. Merged cells may cause issues
4. Multi-page tables need manual merge

### Data Cleanup
After conversion, check:
- [ ] Column alignment
- [ ] Number formatting
- [ ] Date formats
- [ ] Merged cell handling
- [ ] Header row detection
```

### PDF to Images

## Troubleshooting

### Common Issues
| Problem | Cause | Solution |
|---------|-------|----------|
| Text not selectable | Scanned PDF | Apply OCR first |
| Missing characters | Font issues | Embed fonts or convert |
| Poor image quality | Low DPI | Use higher resolution |

Overview

This skill converts PDF files to and from Word, Excel, PowerPoint, images, HTML, Markdown, and plain text while aiming to preserve layout and data. It supports single-file and batch jobs, offers resolution and quality options, and includes guidance for OCR and preprocessing scanned documents. Use it to extract text, images, tables, or produce print-ready PDFs from office files.

How this skill works

The skill inspects the PDF source type (native text, scanned image, or mixed) and applies appropriate extraction methods: OCR for image-based PDFs, table detection or area selection for data pages, and layout-preserving or edit-optimized modes for document output. It exposes settings for DPI, quality level, page range, and export format, and provides post-conversion checks and cleanup recommendations.

When to use it

You need editable Word or Excel versions of a PDF for editing or data analysis
Extract images or high-resolution page snapshots from PDFs
Convert multiple documents in a folder into a single target format (batch jobs)
Prepare print-ready PDFs from Word, Excel, or PowerPoint with embedded fonts
Process scanned documents by running OCR before conversion

Best practices

Identify source PDF type: run OCR on scanned or image-based PDFs first
Choose 'Exact' mode for layout fidelity or 'Editable' mode for easier edits
Set DPI appropriate to use case (300 DPI for print, 150 DPI for web)
Check fonts and embed or substitute missing fonts when exporting to PDF
Validate tables and numeric formats after PDF→Excel conversions and adjust merged cells

Example use cases

Convert financial reports (PDF) to Excel for analysis, using table auto-detection
Batch-convert a folder of resumes (PDF) to Word for HR editing
Export slides from a presentation PDF to high-resolution PNGs for a poster
Create archival PDFs from Word files with PDF/A and embedded fonts for long-term storage
Extract product images from a catalog PDF at 300 DPI for e-commerce listings

FAQ

Will conversions perfectly preserve complex layouts?

Complex layouts may shift; use 'Exact' mode to maximize fidelity but expect some manual adjustments for multi-column pages, floating elements, or complex tables.

How do I handle scanned PDFs?

Run OCR first to convert images to selectable text. OCR quality depends on scan resolution and clarity—use 300 DPI or higher for best results.
