Overcoming Excel’s Limitations with Power Pivot and Power Query

2. ETL (Extract, Transform, Load) Process Automation

One of the key features of Power Query is its ability to automate ETL processes. Once you create queries to retrieve, clean, and modify data, the process can be saved and re-run at any time without the need for manual work. This increases efficiency, especially when you’re working with frequently updated data.

If you need to retrieve weekly sales reports from a CSV file, Power Query can automatically combine all the files, clean the data, and present them in a ready-to-use format with just one click.
