Running Python-Based ML Tasks In Excel

Tony Roberts shows off some of the functionality of PyXLL:

Once we’ve done the hard work of building and testing a model we need to put it to some use! Excel is a great front-end tool for playing with data interactively. It’s used virtually everywhere and so being able to deliver your model in Excel to non-developer users massively opens up opportunities for how it can be used in your business. Even if the model is being used as part of a real-time or batch system, being able to call the model interactively can be really helpful when trying to understand the behaviour of a system.

Fortunately now the model is written in Python getting it into Excel is extremely simple. PyXLL, the Python Excel Add-In has everything we need to write Python for Excel. All we need to do is add a few @xl_func decorators from the pyxll module and configure the PyXLL add-in to load the module containing our model.

If you’re not already familiar with PyXLL, check out the introduction to PyXLL from the user guide.

I mean, if the data’s going to live in Excel spreadsheets anyhow…
