The ijs file extension is associated with J, a high-level, general-purpose programming language developed by Jsoftware.
An ijs file contains script written in the J programming language. It can hold executable statements, definitions, and other source code used by a J application or session.
The format remains part of the J software ecosystem and is used for J scripts.
Install J for Microsoft Windows and open the ijs file in J's editor or development environment. The file can then be run or loaded by the J interpreter.
A plain-text editor can display or edit the script, but it cannot execute J code.
An ijs file is source code and has no standard conversion to another file format. Converting it into another programming language requires manual translation and may change its behavior.
