The Chromium profile usually is named Default, but sometimes not. If you cannot find bookmarks there, try
Code:
find ~/.config/chromium -type f -name Bookmarks
The file Bookmarks in Chromium profile is in JSON format. The link provided by
Lucko666 above also explains how to export bookmarks in a HTML file. If, by chance, you want to work with the JSON file directly, this command will simplify its structure:
Code:
jq '..|objects|select(has(type))|select(.type=="url")|{name:.name,url:.url}' Bookmarks
