Dynamic Formatting for Thousands & Millions

Hi all,


I wonder if anyone can suggest a means of using the custom format capabilities of PowerBI to replicate what in Excel would look like this:


[>=1000000] #,##0.00,,"m";[<1000000] #,##0.0,"k";General


Essentially what I'm after is for when the number is in the millions for it to be formatted with two decimal places and have an 'm' appended to the number, when it's in the thousands, a single decimal place and a 'k' appended. I'm aware that I could create a measure using the SWITCH function to do this, but wonder if anyone has come up with a custom format that does the same thing?


Thanks in advance,

Power BI can now do this. It is called dynamic format strings

Hi @TrevLc Thanks for pointing this out. But have you been able to make it work with the "commas" to divde the number by 1000, 1000000 etc.? I tried but it does not seem like it is implemented in the Dynammic format strings?

hi i am wondering if someone could helpme. i tried to change the format to currency and seted up with two decimal places. i got everything righ in other chart but not this multi-row card. I don't know why.


If these are measures, make sure it is set on the measure itself


I have set this and it seems to work for me

In the above screenshot, you can see I have selected the measure - "Total Revenue".

Under the format Tab, the format Is General.

---- Switch the format to Currency.

---- Also adjust the decimal points to two places.




Check the above screenshot. You can check the card which shows Monthly revenue and check the values as they add a "K" or "M" when required.

I am looking for a solution to this too if anyone knows of one?

Rather than writing it into a measure, I would like to do it using the dropdown option to select custom format like you do in Excel

I have also encountered the same issue and was wondering has anyone found a solution for this yet. Even when i set the 

[>=1000000] #,##0.00,,"m";[<1000000] #,##0.0,"k";General

in excel and import into PowerBi, it will clear this.

Thanks for the reply - I think maybe you misunderstood the question slightly: I'm looking to use custom formatting in the Model view to do this rather than in a measure. The ultimate goal being that I can do a quick, non-destructive change to a number's format rather than having to go a write a measure everytime (as per the SWITCH suggestion in my original post). The RADACAD article is useful, but only really for date formats.
