Your question is Automate Excel Process with ETL. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

Describe a time you automated a manual Excel-based process using an ETL tool or Python script.
