I have seen some tomfuckery in my time, but this one is absolutely baffling.

#Excel

@Rhodium103 I'll admit that looks weird, however the reason for running the Python in the cloud is so that a Python payload can't maliciously access resources on your computer, install malware, or otherwise pose a security risk to your assets. Like most security issues, it is a trade-off.

@VisualStuart @Rhodium103

Are there any details on pricing? The press release only mentions that there will be features restricted later as paid.

They use a similar security model as with Excel VBAs: once a Workbook is deemed secure, it executes all the Python in it.

Cloud computing costs and it is easy to write expensive operations in Python or end up in infinite loops. Could Excel-in-Python users end up paying sky high cloud computing bills after opening a Workbook from a co-worker with a cell on sheet 12 calculating the factorial of 5000? With a local execution, you'll at least notice that your excel is slowing down drastically. With cloud execution these costly operations are out of mind.
