What format does this expect?

The Netscape cookie file format — a tab-separated plain text format used by many browser extensions, automation tools (like curl and yt-dlp), and scraping libraries for exporting and importing cookies.

What does an expiry of "Session" mean?

It means the cookie has no fixed expiration date and will be cleared when the browser session ends — the Netscape format represents this as an expiry value of 0.

Can I edit cookies with this tool?

No — this is a read-only viewer for inspecting cookie file contents, not an editor for modifying or re-exporting cookie data.

Is my cookie data sent anywhere?

No — parsing happens entirely in your browser. Cookie values, which can be sensitive session tokens, are never uploaded or sent to a server.

About Cookie File Viewer

Browser cookie exports (used by automation tools, scrapers, and some browser extensions) follow the Netscape cookie file format — a tab-separated plain text layout that's technically readable but genuinely hard to scan by eye, since columns don't visually align without a monospace grid.

This tool parses a Netscape-format cookies.txt file and displays each cookie in a proper table — domain, name, value, path, whether it's secure, and expiry date all in clearly labeled columns, instead of a wall of tab-separated text.

Session cookies (with no fixed expiry) are labeled clearly as "Session" rather than showing a confusing raw zero value, and long cookie values are truncated in the table with the full value available on hover, keeping the table readable even with lengthy session tokens.

How it works

Paste or upload a cookies.txt file. Paste the tab-separated content, or upload a Netscape-format cookie file.
Review the table. See every cookie's domain, name, value, path, and expiry clearly laid out.
Hover to see full values. Long values are truncated in the table but shown in full on hover.

Examples

Single cookie entry

Input

example.com	TRUE	/	TRUE	0	session_id	abc123

Output

A table row: Domain example.com, Name session_id, Value abc123, Expiry Session.
