Often you do the transformation in Power Query using the graphical interface, but having the formula bar visible, makes it much easier to understand or change the transformations. In this short blog and video, I’ll explain that.
Power Query transformations
In Power BI, we use Power Query a lot for transformations, but mostly using the graphical interfact;
To view, or change the transformations, you can always use the Applied Steps. some steps have the great icon beside them, which makes it easier to apply a change.
However, some steps, don’t have the gear icon, and that makes it hard to understand them, or even change the task done there. For example, in the above screenshot, it is not easy to find out what columns has been removed (unless you go to the previous steps and compare what columns are missing in this step manually), let aside to change the configuration.
Power Query Formula Bar
Power Query formula bar is a very useful place to understand the action applied in each step, and also change it if it is needed.
To make the formula bar visible, go to the View tab, and check the Formula Bar;
When the formula bar is visible, each task’s action is visible there. You don’t have to be an M deep-dive developer to understand that. You might need some help in some areas if you are modifying things, but even the formula bar itself there would help you to understand the transformation better.

Hello. In the newest PBI desktop version (2.92.943.0), in Report view I can’t see the formula bar and there is no chance in View to make it visible (Gridlines, Snap to grid and Lock objects are the only ones with tickbox before them). Thanks for checking it out. Br, Márton
The Formula Bar of Power Query is only available in the Power Query Editor window. the menu items you are talking about are Power BI Desktop options.
Click on the Transform Data in the Home tab. this will open a new window named Power Query Editor. In that window, you will have the view tab and you can enable the Formula Bar
