Shift Training Year

Shift year references in training data files (CSV, XLSX) by a specified amount. Designed for annual updates to course training data — handles filenames, CSV content (Order Numbers, dates), and XLSX year columns.

When to Use

• Updating training data files so the years match the current course year
• User says "เลื่อนปี", "shift year", "update year in data/training files"
• Preparing Power BI, Excel, or data analytics training materials for a new year

How It Works

Run the bundled script which handles everything:

python "<skill-path>/scripts/shift_year.py" "<folder-path>" [--shift N] [--dry-run]
