Python in Excel

>"With Python in Excel, you can type Python directly into a cell, the Python calculations run in the Microsoft Cloud, and your results are returned to the worksheet, including plots and visualizations."

I interpret that to mean your workbook is local to your computer but the python calculation is performed remotely and the result is then returned to your local workbook and stored in the cell.

Beyond latency concerns, I imagine there have to be security and privacy issues.
