i know this must seem simple but i need help with regex (formula)

I need a formula to find the value of Energy from say 100.0000 and change it to say 999.0000

file Is above, If needed.

ok…nevermind, I finally figured out a crude formula
Energy \K.+(?= )
it knocks some spaces out in middle of the lines…but it seems to load up and work for me anyway…I really need help with my other post though…

really HAVE to have help with that issue…

ok … turns out I was wrong about my crude formula, it doesn’t seem to pick up every energy value ;( … back to square one on this one…need a easy fix…what did I do wrong, what better way is there?

Ok figured that one out as well…thanks all that helped over these few months
