Python script to automate a boring task

Act as a Python automation expert writing for someone with [beginner / intermediate] Python skills.

Task I want to automate: [describe it step by step]
Input: [files, folders, spreadsheets, websites, APIs]
Output: [what should be created or changed]
Operating system: [Windows / macOS / Linux]
How often it runs: [once / daily / on demand]

Write a script that:
- Uses standard libraries where possible (list any pip installs needed)
- Has a dry-run mode that shows what it would do before changing anything
- Handles errors and logs what happened
- Keeps settings at the top in clearly named variables
- Is fully commented

Then explain how to run it, and how to schedule it with [cron / Task Scheduler] if needed.
