Frequently asked questions

What is a YouTube Data Viewer?
A YouTube Data Viewer is a free tool that shows public details from a YouTube video URL, including the title, thumbnail, tags, hashtags, views, likes, duration, description, and channel information. DataViewer works in your browser with no login required.
How do I get YouTube video details from a link?
Copy a YouTube video URL, paste it into DataViewer, and click Analyze. The tool will fetch the available video metadata and show the title, thumbnail, tags, hashtags, stats, duration, description, and channel details in one place.
Can DataViewer recommend useful YouTube tags?
DataViewer extracts the tags already used on a video so you can study what creators include in their metadata. You can use those tags as research for your own videos, but always choose tags that accurately match your content.
Can I download YouTube thumbnails?
Yes. After analyzing a video, you can preview and download the available YouTube thumbnail sizes, including HD quality when YouTube provides it.
Can I see hidden YouTube video tags?
Yes. When tags are available in the video metadata, DataViewer displays the creator's YouTube tags that are normally hidden on the YouTube watch page. You can copy the tags with one click.
Is this YouTube Data Viewer free to use?
Yes. DataViewer is free to use and does not require an account, login, or API key. Paste a YouTube URL and view the available video details instantly.
Does DataViewer process pasted JSON, CSV, or XML locally?
Yes. The local string preview on DataViewer runs in the browser, turns pasted JSON arrays, CSV rows, XML nodes, or plain text into a matrix preview, and keeps raw paste zones out of snippet-targeted page content.
Why is DataViewer safe for quick metadata checks?
DataViewer keeps the workflow zero-login, marks active paste environments with data-nosnippet, and reserves output containers before data injection to protect privacy and reduce layout shift.
Does DataViewer work with YouTube Shorts?
Yes. DataViewer supports common YouTube URL formats, including youtube.com/watch links, youtu.be links, Shorts URLs, and embed URLs.
