What Our Users Say

Jolanda Stadelmann

We use xlwings to automate the data feeds of one of our analytical spreadsheet tools, which saves us 1–2 days of tedious manual work every month. Data sources include REST APIs, CSV files via SFTP, and web scraping.

Adam Wood, CFA

xlwings has saved me hundreds of hours in my current role. I replaced the VBA reporting with it and instead of taking 20–30 hours a month I can get the reports run in 6–7 hours.

You're in good company


Leverage Python's scientific stack for interactive data analysis using Jupyter Notebooks, NumPy, Pandas, scikit-learn etc. Or use xlwings to automate Excel reports with Python (Windows & Mac).


Write Excel tools with Python instead of VBA and call your code directly from within Excel, e.g. via a button on the sheet. This also works great for prototyping web apps (Windows & Mac).


Write (array) UDFs in a breeze by taking advantage of all the functionality already available in libraries like NumPy and Pandas. Since v0.10, dynamic array formulas are supported (Windows only).


Expose your workbooks via REST API and access them from other computers in your corporate intranet or over the web. See the REST API docs.
