    };
    const json_editor = new JSONEditor(document.getElementById("json_editor"), {mode: 'code'}, placeholder);
    const tree_editor = new JSONEditor(document.getElementById("tree_editor"), null, placeholder);
    tree_editor.expandAll();

    function toTree() {
        tree_editor.set(JSON.parse(json_editor.getText()));
        tree_editor.expandAll();
    }

    function toJson() {
        json_editor.setText(JSON.stringify(tree_editor.get(), null, 2))
