Twitter URL expander

twitter_url_expander.md

Source: Claude.ai

I've created a Python script that expands t.co URLs in a Twitter archive. Here's how to use it:

1. Install the required packages:

pip install requests tqdm

2. Run the script with your Twitter archive path:

python twitter_url_expander.py /path/to/twitter/archive

Key features:

• Processes all tweet.js files in the archive
• Creates backups of modified files
• Caches expanded URLs to avoid redundant requests
• Shows progress with a progress bar
• Handles errors gracefully
• Uses concurrent processing for better performance
• Maintains the original file format and structure

The script:

1. Finds all tweet.js files in the archive
2. Processes each file to find t.co URLs
3. Expands URLs using HTTP HEAD requests (to avoid downloading full pages)
4. Updates the JSON with expanded URLs
5. Creates backups of modified files
