How does it tell host:port:user:pass from user:pass:host:port?

It looks for a valid port (1 to 65535) after a valid IP or hostname. If the second field is a port, the line is read as host:port:user:pass; if the last field is, it is read as user:pass:host:port. Passwords containing colons are kept whole.

Which format should I use?

Whatever your tool expects. Browsers' proxy extensions and many bots take host:port:user:pass; cURL, Python requests and Node libraries take URLs such as http://user:pass@host:port; spreadsheets and databases are easiest with CSV or JSON.

What happens to special characters in passwords?

In URL formats, usernames and passwords are percent-encoded (for example @ becomes %40) so tools parse them correctly. Other formats keep them as typed.

Does it support IPv6 proxies?

Yes, when the address is written in brackets, such as [2001:db8::1]:8080. Outputs keep the brackets wherever a port follows the address.

Supported proxy formats

The formatter reads every layout below, line by line, and can write any of them.

Format	Example
host:port:user:pass	203.0.113.10:8000:user:pass
user:pass@host:port	user:pass@203.0.113.10:8000
user:pass:host:port	user:pass:203.0.113.10:8000
host:port@user:pass	203.0.113.10:8000@user:pass
HTTP URL	http://user:pass@203.0.113.10:8000
SOCKS5 URL	socks5://user:pass@203.0.113.10:8000
host:port (no credentials)	203.0.113.10:8000
CSV (host,port,user,pass)	203.0.113.10,8000,user,pass
JSON array	[{"host":"203.0.113.10","port":8000,…}]

Which tools expect which format

Anti-detect browsers and extensions

Usually host:port:user:pass, one per line, with the protocol chosen separately.

cURL, Python and Node.js

A proxy URL: http://user:pass@host:port for HTTP(S) proxies, socks5://user:pass@host:port for SOCKS5.

Scrapers and bots

Often user:pass@host:port or host:port:user:pass; check the tool's import screen for an example line.

Spreadsheets and databases

CSV with a header row, or JSON objects with host, port, username and password fields.

Merging lists from several providers? Paste them all at once: every line is read on its own, duplicates are removed and lines that can't be read are listed so you can fix them.

Frequently asked questions

No. The formatter runs entirely in your browser; the list and its credentials never leave your device.
