Deciding whether to use Power Query or VBA macros for data transformation depends entirely on your workflow architecture. Power Query excels at repeatable data importing and cleaning, while VBA provides user interface automation and custom logic triggers. Learn when to use each for maximum efficiency.
When Power Query is the Winner
For importing messy CSVs, unpivoting columns, appending monthly sales logs, and merging ERP queries, Power Query is faster, requires no code maintenance, and refreshes seamlessly.
When VBA Macros are Essential
When your process requires saving individual worksheets as password-protected workbooks, automating emails via Outlook, or controlling external applications, VBA remains the unmatched automation engine.
