How do I set character width from JSON?

Hello,

I went and grabbed a font from the internet, got GYFM ( By blackhornet ) and made a spritefont with it.

I've made it to work with good spacing with many actions. I'd like to know how to set every character width with the JSON exported from GYFM.

I've tried SpriteFont -> Set from JSON but it didn't work.

Cheers,
