Does Requests parse CookieMan JSON directly?

No. Use Netscape + MozillaCookieJar, or iterate the JSON and session.cookies.set(name, value, domain=..., path=...).

Why does MozillaCookieJar skip my lines?

Spaces instead of tabs, or a missing newline. Re-export from this converter. Session rows use expiry 0; that is valid.

http.cookiejar vs requests.cookies?

requests.Session.cookies is a RequestsCookieJar that wraps cookiejar. Assigning a loaded MozillaCookieJar works. httpx is a different client — httpx cookies from Netscape.

Python Requests CookieJar from JSON

Load a Requests CookieJar from JSON or cookies.txt

Python Requests loads Netscape files with http.cookiejar.MozillaCookieJar; convert a Chrome JSON export to cookies.txt here, then jar.load() before requests.get.

A JSON map of name→value is not enough for a jar: it has no domain. If you only have a map, convert to JSON Array, set domain, then export Netscape.

1
Get a full-fidelity export
CookieMan JSON Array, not a JSON map. Maps default every cookie to localhost — JSON Map vs JSON Array.
2
Convert to Netscape
Paste the array. Download cookies.txt. HttpOnly becomes #HttpOnly_, which MozillaCookieJar understands.
3
Load the jar in Requests
Use the snippet below. Point requests.get at a URL whose host matches column 1 of the file.

Output

Cookies are credentials. Conversion stays in this page — delete the file when you are done.

Working Requests snippet

            from http.cookiejar import MozillaCookieJar
import requests

jar = MozillaCookieJar("cookies.txt")
jar.load(ignore_discard=True, ignore_expires=True)
session = requests.Session()
session.cookies = jar
response = session.get("https://example.com/dashboard")
print(response.status_code)

ignore_expires=True loads expired rows for debugging. Do not ship that flag in production jobs. Cookie files are credentials — keep them out of source control.

Header-only alternative

If you only need one call and do not care about Domain matching, convert to Header String and pass headers={"Cookie": "..."}. That bypasses the jar and will not store Set-Cookie from the response unless you also use a Session.

Input you have	Convert to	Requests API
JSON Array with domains	Netscape	`MozillaCookieJar.load`
JSON Array	Header String	`headers={"Cookie": ...}`
JSON Map	JSON Array, then edit domains	Do not load a map as a jar

JSON Map vs JSON Array Cookie Export

A JSON map is name→value only. CookieMan fills domain=localhost, path=/, session=true and warns. Use JSON Array when you need to import into Chrome.
