The cl file extension is associated with the Lisp (or LISP) programming language. Lisp is a family of computer programming languages that was  originally specified in 1958. Today, the most widely known general-purpose Lisp dialects are Common Lisp and Scheme.

The cl file contains source code written in Common Lisp programming language. It is a simple text file that can be opened in various text editors. However it is better to edit source code with text editors that support Common Lisp source code highlighting.
