About two years ago I wrote a blog post on how to connect to a Power BI Desktop model from different tools like SSMS, Excel and SQL Server Profiler. A big chunk of that blog post was about different ways of finding Power BI Desktop local port. Having the port number is crucial if you want to connect to a Power BI Desktop model from any sort of tools for different purposes like monitoring in SQL Server Profiler or analysing the model in Excel. I’m asked several times here and there about different scen people need to find Power BI Desktop local port number, so I decided to dedicate a post to Power BI Desktop local port number.

Therefore, if you want to connect to the model to analyse it in Excel you need to know that port number. There are several ways to achieve that port number which this post will cover most of them.
As you may know, Power BI Desktop is now available as a Windows App that can be installed from Windows Store. In general, the main difference between the App and the downloaded edition from Micrsosoft website is that you will get notification whenever a newer version is available to download. Then you have to manually download and install the newer version on your machine, but, the App will be updated automatically. But there are some other differences that are out of scope of this article. There is just one difference which is relevant to this article which is that Power BI Desktop creates its temporary folders in a different location than the Power BI Desktop App does.
The methods described in this post works for both downloaded edition and the Store edition.

The reason that I explain different methods is that not all methods are doable in all environments. You may work at a customer site that doesn’t allow you to install new software like DAX Studio on their machines. But you always have access on Power BI Desktop temporary files.
