+# Filter Lines Through An External Program
+
+Vim allows you to filter lines from your current buffer through an external
+program. For instance, if you have some ugly looking json that you'd like to
+format in a readable way, you might want to filter it through an external
+json pretty printer program.
+
+To filter the entire file through an external program, use
+
+```
+:%!! <external-program>
+```
+
+Or you can make a visual selection and just filter that
+
+```
+:'<,'>!! <external-program>
+```
+
+See `:h !!` for more details.
