md-to-pptx

Convert Markdown to PowerPoint or generate presentations with AI assistance.

Dependencies

Install required packages before use:

pip install python-pptx Pillow

Note: Use python3 instead of python on systems where Python 3 is not the default.

Workflow

Step 1: Gather Requirements

IMPORTANT: Before generating any content, you MUST ask the user the following questions using the AskUserQuestion tool:

1. PPT页数 (Slide Count): 您希望PPT包含多少页？

   • Options: 5-10页, 10-15页, 15-20页, 20页以上

2. 面向用户群体 (Target Audience): 这个PPT的目标受众是谁？

   • Options: 企业高管/决策者, 技术团队/开发者, 学生/教育场景, 普通大众/客户

3. PPT演示场景 (Presentation Context): 这个PPT将在什么场景下使用？

   • Options: 商务汇报/会议, 产品发布/路演, 培训/教学, 学术报告/研究分享

4. PPT模板选择 (Template Selection): 是否使用已有的PPT模板？

   • Options:
     • business (商务风格 - 白色背景，深蓝标题)
     • tech_dark (科技风格 - 深色背景，绿色点缀)
     • education (教育风格 - 暖色背景，橙色点缀)
     • neumorphism (新拟态风格 - 蓝黄色现代风格)
     • 不使用模板/自定义

Additional questions to ask:

5. Source: Do you have an existing Markdown file, or should I generate content?
6. Save location: Where to save the PPT? (default: user's current working directory)

Use the answers to guide content generation:

• Slide Count: Determines the depth and detail of content
• Target Audience: Affects language complexity, terminology, and examples
• Presentation Context: Influences tone, structure, and visual style
• Template: Sets the visual theme for the presentation

Step 2: Determine Approach

If converting existing Markdown:

1. Read the Markdown file
2. Parse content into slides (H1/H2 headings create new slides)
3. Generate PPTX with appropriate layouts

If generating new content:

1. Create an outline based on user's topic
2. Present outline for user approval
3. Generate full Markdown content
4. Convert to PPTX

Step 3: Generate Presentation

Run the conversion script:

python scripts/md_to_pptx.py input.md -o output.pptx --theme business

Command Line Options

python scripts/md_to_pptx.py <input.md> [options]

Options:
  -o, --output      Output filename (default: input name + .pptx)
  -d, --directory   Output directory (default: user's current directory)
  -t, --theme       Theme: business, tech_dark, education, neumorphism
  --template        Path to custom .pptx template
  --no-template     Generate without using built-in template
  -q, --quiet       Suppress progress output
  --list-themes     Show available themes
  --list-templates  Show template locations

Examples

# Save to current directory (default)
python scripts/md_to_pptx.py presentation.md

# Specify output filename
python scripts/md_to_pptx.py presentation.md -o slides.pptx

# Save to Desktop
python scripts/md_to_pptx.py presentation.md -d ~/Desktop

# Use tech dark theme
python scripts/md_to_pptx.py presentation.md --theme tech_dark

# Use neumorphism theme
python scripts/md_to_pptx.py presentation.md --theme neumorphism

# Use custom template
python scripts/md_to_pptx.py presentation.md --template company.pptx

# Show available themes
python scripts/md_to_pptx.py --list-themes

# Show template locations
python scripts/md_to_pptx.py --list-templates

Built-in Templates

Four pre-built templates are included in assets/templates/:

| Template | File | Description | |----------|------|-------------| | business | business_template.pptx | White background, dark blue titles, professional | | tech_dark | tech_dark_template.pptx | Dark gray background, green accents, developer-friendly | | education | education_template.pptx | Warm cream background, orange accents, approachable | | neumorphism | 蓝黄色新拟态行业调研报告PPT模板.pptx | Blue-yellow neumorphism style, modern research report |

Custom Templates

Place custom .pptx templates in assets/templates/ or specify path with --template:

# Use template from assets/templates/
python scripts/md_to_pptx.py input.md --template assets/templates/my_company.pptx

# Use template from any location
python scripts/md_to_pptx.py input.md --template /path/to/custom.pptx

To regenerate built-in templates:

python scripts/generate_templates.py -o assets/templates

Markdown Format

Key rules: # H1 creates title slide, ## H2 creates content slides, ### H3+ stays on current slide.

For detailed format reference including supported elements, image handling, and layout selection, see references/markdown-format.md.

Error Handling

The generator uses fault-tolerant mode:

• Unsupported elements are skipped with warnings
• Missing images show placeholder text
• Malformed tables fall back to text
• All warnings are collected and reported at the end

Progress Feedback

The script reports progress per slide:
