In VS Code is the an opposite command from join lines? Like, expand lines?

How to expand a line of code? For example join lines command will do this

before

{
  a: 123,
  b: 321
}

after

{ a: 123, b: 321 }

And I need to do the opposite,

from this

{ a: 123, b: 321 }

to this

{
  a: 123,
  b: 321
}

Is there a way to do it? Maybe a plugin? Thanks.

How do you go one line down in VS code?

If you put the cursor on a line of code and use the Alt+Up Arrow keys, the line of code you've selected moves up. If you use the Alt+Down Arrow keys, the line of code selected moves down.

I noticed the example you provided wasn't valid JSON (missing quotes). If it was, or was any other valid type of code you could use the built VS code code formatter:
