How to achieve such format?

Hi, Anonymous 

You can try following steps to transform data

1.Click 'Transform Data' and change the column type to 'Text'

2. Replace character' ' with character '.' and replace character ',' with character ''

3.Change the column type to 'Decimal Number' and  click 'Close & Apply'

4.Then you can use custom format strings in Power BI Desktop to customize how fields appear in visuals
