Matt Allington is back from the future:
The ability to apply custom format strings directly inside the Power BI Desktop report view was first announced back in February 2020. At the time I was quite excited and tweeted about it only to find out shortly thereafter that it hadn’t been released at all! It seems it was a release candidate that was pulled at the last minute, but no one updated the announcement! Then late last week I was doing some work in Power BI desktop and noticed that this feature has now been released and is working (I don’t recall seeing a new announcement at all).
Below I show you how to use custom formatting strings in Power BI.
