# Python Workflows. Inside Excel. With xlwings Lite (free) - Powerful.

Data transforms, automations, custom functions, API Calls, stats, ML

Another superb addition to analyst and data scientist's toolkit - xlwings Lite. From [Felix Zumstein](https://www.linkedin.com/in/felix-zumstein/), creator of xlwings - the powerful and widely used Python package for Excel automation. I've used xlwings off and on over the years - solid package.

**xlwings Lite** was released just yesterday. Ran a few quick codes- what I typically run in Jupyter / Colab - it's brilliant.

Setup was simple - just add the xlwings Add-in and you're set. Tried an XGBoost model on cleaned-up mock data - decile table, scoring, ROC/Gains chart ...just to see how it handles...Also some quick analysis, feature engineering, basic stats - smooth and easy.

## Most impressive

* Manipulate Excel objects - sheets, columns, rows
* Transfer data between Excel and Python
* Neat mini editor
* Console for print() output and debugging
* Requirements.txt for package installs
* Custom Functions
* Web API calls (huge)+ DB access via same layer (yet to try out)

## Quick Tips (based on initial hands-on)

* Format Excel ranges as Tables - good practice anyway.
* Use any LLM or AI coder - they already "know" the xlwings object model.
* Write everything as standard Python functions (def).
* Use @func to create Excel-callable functions (=formula), and @script for direct code runs.
* Great docs and API reference if you get stuck.

## Is it a replacement for Jupyter/Colab?

Nopes..many analytics and ML workflows are iterative and need data warehouse connects. A strong addition to the toolkit, not a replacement.

## Great fit for

* Excel automation - I'll take Python over VBA any day (and the combo - even more powerful)
* Complex data transformations - no need to switch between Jupyter and Excel.
* In-Excel EDA, validations, diagnostics
