Extract Text Inventory

Get all text content from an existing presentation:

{
  "pptx_path": "/path/to/presentation.pptx"
}

Returns structured JSON:

{
  "slide-0": {
    "shape-0": {
      "left": 0.5,
      "top": 1.0,
      "width": 12.0,
      "height": 1.5,
      "paragraphs": [
        {"text": "Title Text", "font_size": 44.0, "bold": true}
      ]
    }
  }
}

Replace Text Content

Modify text in an existing presentation:

{
  "pptx_path": "/path/to/template.pptx",
  "output_path": "/path/to/output.pptx",
  "replacements_json": {
    "slide-0": {
      "shape-0": [
        {"text": "New Title", "font_size": 44, "bold": true}
      ]
    }
  }
}

Rearrange Slides

Reorder, duplicate, or remove slides:

{
  "template_path": "/path/to/template.pptx",
  "output_path": "/path/to/output.pptx",
  "slide_sequence": "0,2,2,1,3"
}

• 0,2,2,1,3 → Keep slide 0, duplicate slide 2, then slides 1 and 3
• Omit an index to delete that slide

Unpack/Pack for XML Editing

// Unpack to directory
{
  "office_file": "/path/to/document.pptx",
  "output_dir": "/path/to/unpacked"
}

// Pack back to file
{
  "input_dir": "/path/to/unpacked",
  "output_file": "/path/to/output.pptx"
}

🔧 Troubleshooting

# Check which Python pip uses
pip --version

# Install with specific Python
/path/to/python -m pip install -e .

# macOS
brew install --cask libreoffice && brew install poppler

# Linux
sudo apt-get install libreoffice poppler-utils
