Cookie Exporter | Netscape, JSON, Header

Exports browser cookies in Netscape, JSON, or header format — compatible with curl, wget, yt-dlp, aria2, HTTPie, and more.

Replaces Get cookies.txt LOCALLY — no browser extension needed, works entirely through your userscript manager.

Why You Need This

Downloading authenticated content requires valid cookies. Dedicated cookie extensions exist, but they add another icon to your toolbar, another permission to manage, and another update to track. This script uses your userscript manager's built-in GM_cookie API — no separate extension needed.

Key Features

Menu Command: Use the Violentmonkey/Tampermonkey menu to export cookies for the current site or all sites.
Multiple Formats: Choose between Netscape (curl, wget, yt-dlp), JSON, or header format — cycle via the menu command.
Full Auth Cookies: Includes HttpOnly cookies (SAPISID, SID, SIDCC, etc.) — just enable one setting in your userscript manager.
API Auto-Detection: Works with GM_cookie callback, object, and promise APIs across browsers.
Fallback Chain: Tries URL → domain → all-cookies fallback if a scoped query fails.
Visual Feedback: Toast notification on success with cookie count.
Setup Banner: If the API is unavailable, a guided overlay shows exactly which settings to enable.

Usage

Action	Result
VM/TM menu → Export Cookies	Export cookies for current site
VM/TM menu → Export All Cookies	Export cookies for all sites
*VM/TM menu → Format: name* (click to change)**	Cycle through Netscape, JSON, header

Enable HttpOnly Access (One-Time)

The export includes auth cookies by default. To include HttpOnly cookies:

Violentmonkey (Beta v2.35.1+):

Settings → Advanced → Script settings → Enable "Allow GM_cookie to access HTTP-only cookies"
Also enable it in this script's Settings tab

Tampermonkey:

Settings → Config mode: Advanced → Security → "Allow scripts to access cookies" → All

Running the Exported File

curl -b www.youtube.com_cookies.txt "https://example.com"
wget --load-cookies=www.youtube.com_cookies.txt "https://example.com"
yt-dlp --cookies www.youtube.com_cookies.txt "https://youtube.com/watch?v=..."
aria2c --load-cookies=www.youtube.com_cookies.txt "https://example.com"
http -b @www.youtube.com_cookies.txt "https://example.com"

How It Works

Detects which GM_cookie API variant the userscript manager exposes (callback, object, promise).
Queries cookies for the current site via the browser's extension API.
Retries with domain then empty details if the URL-scoped query fails.
Converts to the selected format (Netscape, JSON, or header).
Triggers a file download as example.com_cookies.txt.
Format selection persists across sessions.

Compatibility

Manager	Status
Tampermonkey	✅ Full support
Violentmonkey	✅ v2.35.1+ (enable HttpOnly per above)
Greasemonkey	❌ GM_cookie not supported

The exported file works with any tool that accepts Netscape cookie files — notably curl, wget, yt-dlp, aria2, and HTTPie. This is the same format used by the original Netscape browser and adopted by curl; it remains the standard for passing browser cookies to command-line HTTP tools.

Installation

Install Violentmonkey or Tampermonkey
Install this script
Visit any site and use the VM/TM menu → Export Cookies

No configuration required. For full auth cookie export including HttpOnly cookies, enable cookie access in your manager's settings (see above).
