Cookie Parser
Parse and inspect cookie header strings into key-value pairs
About Cookie Parser
Breaks a cookie string into a two-column table of names and values, splitting it at each semicolon and separating every name from its value. Repeated names are kept in their original order, so duplicate or shadowed cookies are easy to spot. Parsing happens entirely in your browser, which matters when the string holds live session tokens.

Frequently asked questions
What is a Cookie header?
▾
An HTTP request header sent by the browser containing all cookies for that domain, formatted as semicolon-separated name=value pairs: Cookie: session=abc123; theme=dark.
Can I paste the whole Cookie: or Set-Cookie: line?
▾
Paste only the part after the header name. The parser doesn't recognize a Cookie: or Set-Cookie: prefix, so it would end up in the first cookie's name, for example Cookie: session.
Does it understand Set-Cookie attributes like HttpOnly or Max-Age?
▾
It lists them without interpreting them: flags such as HttpOnly and Secure appear as names with an empty value, and attributes such as Max-Age=3600 or Path=/ appear as regular pairs. Nothing is validated, and Expires dates aren't converted.
Are cookie values URL-decoded?
▾
No. Values are shown exactly as written, so percent-encoded text such as %7B stays encoded and surrounding quotes are kept. Everything after the first equals sign belongs to the value, so Base64 padding like abc== is preserved.
