Inspect chrome.storage.sync while debugging Chrome extension

Question

Chrome DevTools has a handy inspector for Local Storage and Session Storage, but is there nothing to inspect chrome.storage.sync?

chrome://sync-internals/ doesn't seem to display the actual contents of the synchronized storage per extension.

Answer 1

Storage Area Explorer extension provides a UI for viewing, editing, clearing, importing and exporting of chrome.storage.local, chrome.storage.sync, localStorage and sessionStorage:

Answer 2

A poor workaround is to call get and obtain all the stored values. Of course, this doesn't let you conveniently edit them:

chrome.storage.sync.get(null, function callback(items) { console.log(items) });
