Using Jupyter Notebooks as Blog Posts

Yes! You can use Jupyter notebooks as blog posts. This guide shows you how.

🎯 Quick Start

Option 1: Convert Notebook to Markdown (Recommended)

Use the provided conversion script:

cd blog
python3 convert_notebook_to_post.py your_notebook.ipynb --date 2026-01-15 --title "Your Post Title"

This will:

• Convert your notebook to a Markdown file in _posts/
• Preserve code cells with syntax highlighting
• Save output images to assets/images/notebooks/
• Generate proper Jekyll front matter

Option 2: Manual Conversion

1. Export notebook to Markdown:

   jupyter nbconvert --to markdown your_notebook.ipynb
   

2. Add Jekyll front matter to the generated .md file:

   ---
   layout: post
   title: "Your Post Title"
   date: 2026-01-15
   categories: [data-science, tutorial]
   tags: [jupyter, python, data-analysis]
   author: Your Name
   ---
   

3. Move to _posts/ with proper naming:

   mv your_notebook.md _posts/2026-01-15-your-post-title.md
   

4. Move images to assets/images/ and update paths in the markdown

📝 Detailed Instructions

Using the Conversion Script

1. Place your notebook in the blog directory (or any location)

2. Run the conversion:

   python3 convert_notebook_to_post.py \
     notebooks/my_analysis.ipynb \
     --date 2026-01-15 \
     --title "My Data Analysis Tutorial"
   

3. Review the generated post in _posts/

4. Edit if needed:
   • Update categories and tags
   • Add description for SEO
   • Adjust formatting
   • Add more context
5. Test locally:

   bundle exec jekyll serve
   

6. Deploy:

   git add _posts/2026-01-15-my-data-analysis-tutorial.md
   git commit -m "Add notebook post: My Data Analysis Tutorial"
   git push
   

🔧 Advanced Usage

Custom Output Path

python3 convert_notebook_to_post.py notebook.ipynb \
  --output _posts/2026-01-15-custom-name.md \
  --title "Custom Title"

Preserve Notebook Metadata

The script automatically extracts:

• Title from notebook metadata (if available)
• Language from kernel specification
• Code cells with proper syntax highlighting

Handling Images

The script automatically:

• Extracts images from notebook outputs
• Saves them to assets/images/notebooks/notebook-name/
• Updates image references in the markdown

📊 Best Practices

1. Clean Up Your Notebook First

Before converting:

• Remove unnecessary cells
• Add clear markdown explanations
• Ensure code is well-commented
• Test that all cells run successfully

2. Add Context

After conversion, enhance the markdown:

• Add an introduction
• Explain the methodology
• Add conclusions
• Include links to related posts

3. Optimize Images

• Use high-quality images for outputs
• Compress large images
• Use descriptive alt text
• Consider using SVG for plots when possible

4. Code Formatting

The script preserves code cells. Ensure:

• Code is readable
• Comments are clear
• Variable names are descriptive
• Follows Python/R best practices

🎨 Example Workflow

Step 1: Create Your Notebook

# In your Jupyter notebook
# Cell 1 (Markdown):
# # My Data Analysis Tutorial
# 
# This tutorial shows how to analyze RNA-seq data.

# Cell 2 (Code):
import pandas as pd
import matplotlib.pyplot as plt

# Cell 3 (Code):
data = pd.read_csv('data.csv')
data.head()

Step 2: Convert

python3 convert_notebook_to_post.py \
  rnaseq_analysis.ipynb \
  --date 2026-01-15 \
  --title "RNA-seq Data Analysis Tutorial"

Step 3: Review Generated Post

The generated file will have:

• Proper front matter
• Code blocks with syntax highlighting
• Outputs preserved
• Images saved and referenced

Step 4: Enhance

Edit the generated markdown to add:

• Better introduction
• More explanations
• Links to resources
• Related posts section

🚀 Alternative: Using nbconvert Directly

If you prefer more control:

# Convert to markdown
jupyter nbconvert --to markdown notebook.ipynb

# This creates:
# - notebook.md (markdown file)
# - notebook_files/ (images directory)

# Then manually:
# 1. Add Jekyll front matter
# 2. Move to _posts/ with date prefix
# 3. Move images to assets/images/
# 4. Update image paths in markdown

🔍 Troubleshooting

Images Not Showing?

1. Check image paths are relative to site root
2. Ensure images are in assets/images/
3. Use /assets/images/... in markdown

Code Not Highlighting?

• Ensure language is specified in code blocks
• Check that Prism.js is loading (already configured)
• Verify code block syntax: ` python ` not ` python `

Outputs Not Preserved?

• The script preserves text outputs automatically
• For HTML outputs, they’re embedded directly
• For images, they’re saved and referenced

Date Format Issues?

• Use format: YYYY-MM-DD
• Example: 2026-01-15
• The script validates the format

💡 Tips

1. Keep notebooks organized: Use clear cell structure
2. Add markdown cells: Explain what each code section does
3. Test before converting: Ensure notebook runs without errors
4. Review output: Check the generated markdown looks good
5. Version control: Keep both .ipynb and .md files if needed
