My day job involves hours of manual data extraction and reporting in spreadsheets. I want to learn Python/SQL effectively to completely automate these workflows. Where should an operations professional focus to build custom automated scripts quickly?

To automate corporate workflows, focus your learning on database connectivity and scripting. Master SQL data extraction using WHERE filters and date functions to pull specific report periods. In Python, focus your energy on learning libraries like psycopg2 or SQLAlchemy for database connections, along with openpyxl or pandas to format data. By combining these, you can write a single script that extracts database records, structures an Excel report, and sends it out automatically.
Heather, that automation workflow would save me hours of manual labor. Once these scripts are written, how do we handle scheduling them? Do we need specialized infrastructure, or can a standard office computer manage automated script execution?
Focus heavily on error handling. When automating reports, an unexpected missing data value or a database timeout can break your script entirely if it isn't coded properly.
That is an incredibly vital tip. Implementing try-except blocks ensures your automated script logs the specific database error instead of silently crashing in the background.
Stephen, you can start simple. Use Windows Task Scheduler or Mac Cron jobs to trigger your Python script locally overnight. As your company scales, you can look into cloud-based cron triggers or orchestration platforms like Apache Airflow.
