Batch change shapes in InDesign to CMYK?

Question

Hi there,
Is there a way to change batch (600shapes) shapes from RGB to CMYK within InDesign?
Thanks

You can also convert all colors both swatches and unnamed colors via a simple script. In AppleScript it would be:
tell application "Adobe InDesign CC 2014"
    repeat with x in every color of active document
        try
            set space of x to CMYK
        end try
    end repeat
end tell
But you can also convert all color to CMYK when you export to PDF, which is the more flexible approach.
