A current limitation in Power BI SWITCH measures (and all Power Pivot actually) is that a SWITCH measure must have a single format. It is currently not possible to conditionally format the measure result based on any criteria - it is one single format only. There are valid use cases where you may want to change the format of the SWITCH measure depending on the result. Consider the following SWITCH statement
myMeasure = SUMX(MeasureTable,switch([selected measure],
1,[Total Sales],
2,[Total Cost],
3,[Total Margin],
4,[Chg Sales vs LY %]
))
The first 3 results are all currency format, but the last result is a percentage format. This currently can't be controlled. I would like to see an optional 3rd parameter in the SWITCH statement to set an alternate number format.

Dynamic format strings are available in calculation groups and can be used to create a DAX expression to handle any format requirement for a pick a measure scenario such as this.

Documentation for dynamic format strings is available at https://docs.microsoft.com/analysis-services/tabular-models/calculation-groups?view=asallproducts-allversions#dynamic-format-strings-for-currency-conversion. And information on external tools to add calculation groups is available at https://aka.ms/externaltools.

There are multiple ways to utilize calculation groups and dynamic format strings and thank you to those who posted solutions in the chat.

Mixing program logic with presentation logic is not a good idea. Since SWICH is syntax sugar for nested IFs, it is equivalent to adding a number format parameter to an IF statement. SWITCH is not the right place for setting conditional number formats. The correct place is in conditional formatting. At the time of this comment, Excel has had the capability for ten years.

Common problem and very important. Please add this!

We also need Custom Number format. So that we can use our own number formats just like excel.

This is also needed for multi currency, which is possibly a more common scenario

It is possible to show different formats in the same column for a TableMatrix as shown below. In a Matrix use the formatting Values option "Show in Rows".

It would be great if this could get some more votes. It is a really necessary change that would greatly assist with formatting in visuals. Please support this one so that we can get Microsoft to look at this.

It's a necessary thing that I need and it would solve a problem that I have often.

This would be fantastic to have
