format multiple columns



is there a way to format multiple columns at once?  This picture does not display the full data, but it basically contains dollar columns where I want to insert commas in each one-and ratios, where I want to add a "%" in all at the same time.  it takes a long time to do them column by column.. I tried control key, but it doesnt work.

Hi @rfway ,


If it is in Power Query, the data type can be set for multiple columns at once. However, in Power BI, formatting multiple columns/measure is not yet possible. 

Did I answer your question? Mark my post as a solution!

I didn't test measures but you can sure change multiple columns at once.

This is a pretty old thread but I will update it with an update, in case anyone needs it.

Go to the Model view in Power BI Desktop and highlight multiple fields. The "Properties" pane will come up and you can change the format of all the fields at once.

I logged in here only to say thank you.  I have spent months searching and no one seems to have found this.  What a lifesaver.

Hi rfway,

Currently, we are not able to format multiple columns at the same time in data view of Power BI Desktop, regarding to this limitation , you can vote it and add comments in the following idea.

In addition, to work around this issue, you can consider to copy the data in Excel and format these columns at once, then re-load the data into Power BI Desktop. There is a similar blog about formatting multiple columns in Excel for your reference.

I've been having this same issue and what I don't understand is, in my Excel source file I have my columns formatted as percentages, in the Power BI query editor, I have my columns formatted as percentages. However in the Power BI main tool, it's converted everything to decimal number format. I wouldn't have this issue if the program wasn't converting the data.


Why does it reformat in the first place from the original source file?

Not applicable

I'm having the exact same issue. I have dozens of columns that I want to change from whole numbers to %'s. They are formatted as % in Excel and in the query editor but not in my data view. Did you find a solution to this? 

Are you trying to do this in Power Query or in the table view in Power Pivot?  You should do it in the former (edit query) - you can definitely multi select there.
