Let your Mac do repetitive tasks for you
If you need to make the same changes to multiple files—such as changing filenames or resizing images—or archive or back up important files, you can create a custom workflow and have your Mac do the work for you.
Script your own actions
If the task you need to automate isn’t in the list of built-in actions, you can add your own scripts, such as AppleScript and JavaScript scripts, and shell commands to your workflow. Simply add the appropriate run script action to your workflow and enter your script code or shell commands.
Use Automator workflows with the Shortcuts app
You can easily import Automator workflows into Shortcuts. Your workflows automatically become a collection of shortcuts ready to run, saving you time and making Shortcuts exceptionally useful right away.
