How to export comments from a YouTube Short
Open the Short (from the Shorts feed, a channel's Shorts tab or a direct youtube.com/shorts/ link), click the InsightSocial icon, pick how many comments you want and press Scrape. The extension opens the comment panel, pauses the Short so it can't swipe to the next one, and opens reply threads as it goes. Export to Excel, CSV, JSON or Google Sheets when it finishes.
The columns are the same as for regular videos: comment text, author, verified and by-the-creator flags, likes, reply count, date, a link to the comment, and the Short's title and channel. Dates come from YouTube's "3 weeks ago" text, so older comments are dated to the month or year.
For a regular video, use the YouTube Comments Scraper. To list a channel's Shorts with their views, use the YouTube Channel Scraper. Comparing the same clip on TikTok? The TikTok Comments Scraper exports the same kind of rows.
