xlwings Lite is out!

Ten years ago, when I started xlwings, I never imagined this would be possible, yet here we are!

🚀 xlwings Lite allows you to create modern Excel add-ins with Python instead of JavaScript WITHOUT THE NEED TO INSTALL PYTHON, not even on the server!

🚀 It's the true "Python in Excel", with Python running on your own machine, inside the browser engine that powers modern Excel add-ins. It's based on Web-Assembly (Wasm) via Pyodide/PyScript.

🚀 Supports custom functions as well as the Excel object model, so you can run scripts that add new sheets etc.

🚀 Supports Windows, macOS, and Excel on the web

🚀 It's the only modern Python in Excel solution with 100% privacy: no trackers, no sign up required, and it can be self-hosted on a static file server like nginx or GitHub Pages.

🚀 Free for non-commercial use.

🚀 xlwings Lite is also the only Wasm-based product that offers a solution if you hit a limitation of Wasm: simply switch 1 setting and you can run everything with a full Python installation on the server. No code changes required.

The possibilities this opens up are amazing. I am currently building my first add-in with xlwings Lite (feel free to guess what it is), which I hope to publish soon in Excel's add-in store. Stay tuned!

Happy coding!
