Export YouTube Comments to CSV with a Simple Tampermonkey Script

Managing YouTube research manually takes time. This lightweight Tampermonkey script helps automate comment collection directly from the YouTube homepage and video feed.

The script scans videos automatically, extracts recent comments, captures author names and “time ago” values, then lets you export everything into CSV format with one click. It is useful for content research, audience analysis, lead generation research, trend monitoring, and social media data extraction workflows.

Unlike heavy browser extensions, this userscript keeps the interface clean with a floating dashboard and quick export buttons inside each video card. It also works well for creators, marketers, and developers working in web scraping, browser automation, and data extraction projects.
