I'm migrating some VBAs to python/pandas and reducing some process times from half an hour to 3 minutes.

Yup that's normal because VBA is single-threaded, doesn't take advantage of vector instructions and even its interpreter is slow. So when someone writes numerical code in VBA working in single precision, and assuming they have an 8 core CPU with AVX2, they're using only 1/64-th of their CPU's processing power. On the other hand with Python, while it's still interpreted, the interpreter is much faster on its own, and you have modules like numpy that use precompiled routines that take advantage of vector instructions (and possibly multiple cores).

Btw, Libreoffice supports python scripts. Other offices too?

Excel will kinda support it soon, unfortunately it will only be available to run in the cloud and not locally.
