Currency formatting in power query editor

[Anonymous]

Hi,

I am trying to format a field "Actuals" to currency in query editor. Unlike desktop, I don't see how to set the format for the field to currency. I am trying to do this in power query so that when I change my datasource, the measures based on that field "Actuals" don't lose its formatting.  Is there a way to format the filed in m query to currency? 

Also, Is there a different way to change the datasource so that I don't lose the formatting on my measures everytime I change the datasource?

You can use format() in Desktop to set measure format to currency. For example: Measure= FORMAT( sum([data]), "Currency")

Thanks, it did let me carry the currency format on measures when I am changing the datasource. But looks like this method is changing the feild to text and therefore when I am trying to do a feild formatting for negative values to be displayed in red colour, its not working.

For Column type - Currency, try this:

Table.TransformColumnTypes(YourTable,{{"YourColumnName", Currency.Type}})

If you have your Source table in raw format, without headers, this is kind of dynamic solution.

In example case, i have used "Sales" string as identifier for column dedicated to currency. I am pretty sure that you have some unique identifier also. Just replace it. 

Until somebody else provides a neater solution, try it. Replace the Source step with your table of course 🙂
