Number format builder
Set how numbers should look, see the result straight away and copy the format string into Power BI.
Format string
Select a measure or column → Format → Custom, and paste the string into the format box.
Dynamic format (DAX)
Select a measure → Format → Dynamic, and paste the expression into the formula bar. The scale adjusts to each value.
How it looks
Power BI takes the separators (space and comma, or comma and dot) from the report’s language settings, not from the format string.
