Is there a JSON beautifier with separate rules for specific keys?

Question

JSON

I want a JSON formatter that, if it encounters a certain key, will format it in the given way.
Those. not this way:

{
    "points": [
        {
            "x": 10,
            "y": 0
        },
        {
            "x": 80,
            "y": 10
        },
        {
            "x": 90,
            "y": 20
        },
        {
            "x": 15,
            "y": 0
        }
    ]
}

Specifically, for the points key

{
    "points": [
        {"x": 10,"y": 0},
        {"x": 80,"y": 10},
        {"x": 90,"y": 20},
        {"x": 15,"y": 0}
    ]
}

If possible, in the form of a js or C/C++ library.
