TL;DR: Paste a video URL into TubeHarvest’s free comment downloader, click Scrape Comments, and it will download youtube comments as CSV, JSON, or Excel in under a minute. No API key, no quota, no code. This guide covers six ways to do it, the exact data you get, and how to choose based on your situation.

Most people scroll past comments. Founders who use YouTube as a growth channel treat them as the cheapest research they have. The trouble is YouTube gives you no way to export them. There is no download button anywhere in the interface, so you have to use a tool, a script, or a workaround.
Here is the complete map, from the fastest no-code option to a developer API, with the tradeoffs spelled out.
Why Download YouTube Comments?
A comment section is an unfiltered focus group. Pulled into a spreadsheet, it becomes something you can sort, search, and act on:
- Audience research. The words viewers use to describe their problem are your headlines. “I have been stuck on this for months” is a landing page waiting to happen.
- Content ideas. Highly-liked questions are your next videos and posts, ranked by demand.
- Competitive intelligence. A competitor’s comment section tells you what their audience wants and is not getting.
- Giveaways and moderation. Picking a winner from 800 comments by hand is miserable. A download makes it a 30-second filter.
The catch is getting the data out. These six methods all do it without touching YouTube’s official API.
The 6 Ways to Download YouTube Comments, Compared
| Method | API key? | Code? | Any public video? | Speed |
|---|---|---|---|---|
| Free web tool (TubeHarvest) | No | No | Yes | Fast |
| Chrome extension (TubeHarvest) | No | No | Yes | Fast |
| Agentic AI browser (Comet, ChatGPT Atlas) | No | No | Yes | Slow, manual |
| TubeAlfred API | No (YouTube’s) | Yes | Yes | Fast |
| Google Takeout | No | No | Your channel only | Slow |
| MCP + Claude/ChatGPT | No | No | Yes | Fast |
Start with the free web tool. Reach for the others only when your situation calls for them.
Method 1: Free Web Tool (Fastest, No Account)
This is the right answer for most people.
Step 1: Open the downloader. Go to TubeHarvest’s YouTube comment downloader. Nothing to install.
Step 2: Copy the video URL. Open any public video and copy its URL. It does not have to be your channel.
Step 3: Paste and scrape. Drop the URL in and click Scrape Comments. It runs on TubeHarvest’s side, so there is no browser tab to babysit.
Step 4: Preview and download. You get a summary first (total comments, unique authors, total likes) and can scan individual rows before committing. Click Download and pick CSV, JSON, or Excel.
The limit: the free tool caps at roughly 250 comments per video per day. Fine for smaller videos; for thousands of comments, the Cloud version lifts the cap and runs server-side.
Method 2: Chrome Extension
If you would rather work on the YouTube page itself, the extension opens in a side panel next to the video. Set a comment limit, choose a speed (Quick, Smart, or Steady), and click Extract. The count climbs in real time, you can pause and resume, and you export to CSV or JSON when done.
Because it reads the page in your own browser, nothing leaves your machine until you export. The free tier covers up to 100 comments per video; a one-time $19 Pro upgrade removes the limit.
Method 3: Agentic AI Browser (Free, No Setup)
For a completely free option with nothing to install, an agentic browser like Comet by Perplexity or ChatGPT’s Atlas can read the page and pull what is on it. Open the video and ask it to extract the visible comments into a list.
The limitation is real: it only sees comments already loaded on screen, and YouTube loads them as you scroll. You will get the first chunk and then have to scroll and re-prompt. Good for a quick read of the top comments, not for complete extraction.
Method 4: The TubeAlfred API (For Developers)
Building something that runs on a schedule or feeds a product? Use the TubeAlfred API instead of scraping by hand. It serves comments from a hosted REST endpoint, with no Google Cloud project and no daily quota.
curl "https://api.tubealfred.com/v1/youtube/video/VIDEO_ID/comments" \
-H "Authorization: Bearer YOUR_API_KEY"There are dedicated endpoints for the comment list, paginated pages, and replies. Pricing is credit-based (1 credit returns 5 comments), and a @tubealfred/cli wraps the same API for terminal and CI use. Best for developers who want reliable access without managing YouTube’s official limits.
Method 5: Google Takeout (Your Own Channel Only)
Google Takeout exports your own account data, including the comment history on videos you own. The hard limit: it only covers your channel. You cannot use it on anyone else’s video.
- Go to takeout.google.com
- Deselect everything, then select YouTube
- Under YouTube data, choose just Comments
- Request the export and wait for the email link
You get a JSON archive of your own comment history. Useful for a personal backup, useless for competitive or audience research.
Method 6: MCP + Claude (Download and Analyze Together)
If you work inside Claude or ChatGPT, you can skip the file entirely. TubeAlfred’s hosted YouTube MCP connects to the assistant, so you ask in plain language (“pull the comments from this video and group the top questions”) and get the comments plus the analysis in one reply. The export step disappears, which is ideal when you are hunting for content gaps rather than archiving data.
What Data Gets Downloaded
| Field | What it is |
|---|---|
| Comment ID | Unique identifier per comment |
| Comment text | Full text, emojis preserved |
| Publish time | Date and time posted |
| Author name | Commenter’s display name |
| Author channel ID | Link to their channel |
| Author avatar | Profile image URL |
| Likes | Likes on the comment |
| Replies | Replies nested under it |
| Comment type | Top-level comment or reply |
Pro tip: Filter to top-level comments first. They are direct reactions to the video and carry more signal than replies when you are mining for ideas and pain points.
Common Snags (and How to Fix Them)
- Comments are turned off. Nothing to download; the data does not exist. Move on.
- Private or age-restricted video. Requires authentication a scraper cannot (and should not) bypass. Stick to public videos.
- Fewer comments than YouTube’s count. Normal. The displayed number includes deleted and spam-filtered comments that will not be in the export.
- The download stopped early. You hit the free tier’s daily cap. Use the Cloud version or wait for the reset.
Which Method Should You Use?
- Just need the data fast, any video: the free web tool.
- Already on the page: the Chrome extension.
- Only the top few comments, zero tools: an agentic AI browser.
- Building a product or automation: the TubeAlfred API.
- Archiving your own channel: Google Takeout.
- Working inside Claude or ChatGPT: the MCP.
Once your file is ready, here is how to work with comments in Excel or Sheets, and what to do with the data after you download it.
