How to examine and edit google-chrome Local Data?

How does google-chrome store its Local Data?

Specifically, I’d like to have a command-line script that would display, or make a few specific changes to, some of the browser’s local data.

I’m not asking how to write the software, but assuming there isn’t already such a tool, I do need to know the specific files and their format.

I see that .config/google-chrome/Default/Cookies is an SQLite database, but I’m interested in Default/Local Storage/leveldb/*.ldb, I think.

(In case it makes any difference, assume Ubuntu 18.04.)
