Create individual macros for each app in the Applications folder

It looks like you started by copying the XML from more than one Action, so you've a rogue opening:

<dict>
	<key>Actions</key>
		<array>

...at the top plus some extra cruft near the bottom.

You can also miss out the ActionUID (which gets regenerated anyway) and all the XML definition and plist stuff -- despite what I posted earlier.

So, assuming you're after:

...this script should do you:

set t to "<dict>
		<key>DisplayKind</key>
		<string>None</string>
		<key>HonourFailureSettings</key>
		<true/>
		<key>IncludeStdErr</key>
		<false/>
		<key>IncludedVariables</key>
		<array>
			<string>9999</string>
		</array>
		<key>MacroActionType</key>
		<string>ExecuteAppleScript</string>
		<key>Path</key>
		<string>/Applications/Adobe InDesign 2026/Scripts/Scripts Panel/DR Delete Rogue Line Endings.scpt</string>
	</dict>"

tell application "Keyboard Maestro"
	tell macro group "InDesign"
		set TheMacro to (make new macro with properties {name:"New Test"})
		make new action at TheMacro with properties {xml:t}
	end tell
end tell

If that isn't what you're after then post a sample KM macro so people can dissect it.

If you are doing a bunch of these you might find it easier to create a single importable XML structure containing all the macros -- see this recent thread for an example.
