Power BI Weekly

Issue #330 - 21st October 2025

This week we've received the Power BI October 2025 Feature Summary, which announces the introduction of the new Power BI Controller in Power BI in PowerPoint (Preview), giving you a centralised way to manage and update all of your Power BI add-ins within a PowerPoint presentation. In your Power BI reports, it is also now possible to Automatically expand table columns to fill available space - eliminating the need for manual resizing and saving so much time! There are plenty more announcements in the feature summary, such as the latest updates in the Transition from Bing Maps to Azure Maps, the GA of Copilot to write DAX queries in DAX query view, and the rollout of the new Performance analyzer in web to see the load times of visuals.

Now onto the other official announcements. There is the introduction of A new Fabric REST API for connection binding of semantic models which gives you a way to programmatically configure and update your connection bindings, and we've also been told about the Improvements to the Report Copilot in Power BI which is available in the Power BI service.

Elsewhere this week, Jon Stjernegaard Vöge has shown how we can use RegEx in Power BI TMDL View for find and replace operations and provides some useful RegEx patterns, and Kenneth A. Omorodion has written a helpful overview on how to create Power BI Custom Calendars for Gregorian, Fiscal, Retail, 13-Month, and Lunar.

Barry Smart has published a 4-part series on The Data Product Canvas: a framework to help you build successful data products. You can read the articles here: Stop Building Data Products That Fail, Deep Dive into the Building Blocks, The Data Product Canvas in Action, and The Theory Behind The Canvas.

Finally, I would like to congratulate Ed Freeman (and of course, his wife Kirsty) on the birth of their first child, a baby boy called Elliot! Ed will be off on paternity leave for the next month; Jessica Hill & I will be guest-editing the Power BI Weekly Newsletter in his absence.
