If you want to inspect your YouTube watch history locally, the first step is getting the correct export from Google Takeout. The important part is not just downloading a zip, but confirming that the export actually contains the watch-history data you expect to inspect.
- Choose the YouTube and YouTube Music data sections carefully in Google Takeout.
- Keep the export local instead of immediately uploading it to third-party tools.
- Open the resulting files with the YouTube Watch History Analyzer inside Small Web Apps so the content stays inside the browser session.
