Remove All Unnecessary Whitespaces from JSON String with regex (in AutoHotKey) - json

Question

How do I remove ALL unnecessary white-spaces from a JSON String (in AutoHotkey)?
I assume that I need to use regExReplace with some clever regex in order to NOT touch the white-spaces that are part of the values.
A simple example would be:
Before:
g_config :=
{
FuzzySearch:{
enable: true,
keysMAXperEntry : 6,
o = {
keyString: "Hello World"
}
}
} ;
After: g_config:={FuzzySearch:{enable:true,keysMAXperEntry:6,o={keyString:"Hello World"}}};
Basically, I'm looking for a way to minify and pack the string as tight as possible without changing any data.
first I tried searching [\n]+ and replace with "" (nothing). Developed here:

Best try: Then I reused this

Problem: this regEx also removes the spaces in a value.
Is it even better to do?

Along the lines of what #Aaron mentioned, here is some slow-as-hell AHK code that will look at each individual character and remove it if it's a space or line break, except between quotes. It starts at your cursor and ends once there is nothing left to copy (or rather, one second after).

}
Return
