Check out this simple library

Hi there, I'm a freelance chrome extension developer and most often I work on data extraction and insertion using extensions.
Hence, I've written this simple tool
that gives you the selector to an HTMLElement.
It's quite accurate than you might be thinking so give it a try.

Note: it currently has some module exports so to get it working without a bundler, you'll want to remove that. I Will host on a CDN soon. Thanks
