xlwings Streaming Functions

Hi all,

xlwings 0.31.0 added support for streaming functions across Windows, macOS, and Excel on the web!

In the traditional version of Excel, streaming functions were called “RTD functions” or “RealTimeData functions”. However, unlike traditional RTD functions, streaming functions don’t use a local COM server. Instead, the process runs as a background task on xlwings Server and pushes updates via WebSockets to Excel. What’s great about streaming functions is that you can connect to your data source in a single place and stream the values to every Excel installation in your entire company. This way, you can easily stay within the API limits of your service.

As a quick reminder: xlwings Server is self-hosted and runs on air-gapped systems without access to the public Internet or any Microsoft server.

To get the details about streaming functions, read the docs:

Happy streaming!
Felix
