Hi everyone, is there a script for batch clipping masks? Thank you

I think I overthought things. The following should make a clipping mask of each two overlapping selected items, whatever the masked artwork is (group, compound path, et cetera).  See if it works for you.

var selectedItems = app.activeDocument.selection;
var a = [];
var test = function(path1, path2) {
    var b1 = path1.geometricBounds;
    var b2 = path2.geometricBounds;
    return (b1[2] > b2[0] && b1[0] < b2[2]) && (b1[3] < b2[1] && b1[1] > b2[3]);
}
for (var i = 0; i < selectedItems.length ; i++) {
    if (!selectedItems[i].done) {
        for (var j = 0; j < selectedItems.length ; j++) {
            if (j != i && test(selectedItems[i], selectedItems[j])) {
                var x = [];
                x.push(selectedItems[i]);
                x.push(selectedItems[j]);
                a.push(x);
                selectedItems[j].done = true;
            }
        }
    }
}
for (var i = 0; i < a.length; i ++) {
    var group = app.activeDocument.groupItems.add();
    a[i][0].moveToEnd(group);
    a[i][1].moveToEnd(group);
    group.clipped = true;
}
