Where Chrome Bookmarks Stored -

You cannot just concatenate two JSON files. You must open both, copy the children array from one bookmark_bar into the other, ensuring you don't duplicate folder IDs (though Chrome regenerates IDs on startup).

Here is a simplified structure:

import json import re with open('Bookmarks', 'r', encoding='utf-8') as f: data = json.load(f) def clean_node(node): if 'children' in node: node['children'] = [clean_node(c) for c in node['children'] if not (c.get('type') == 'url' and 'pinterest.com' in c.get('url', ''))] return node where chrome bookmarks stored
