Plist files, those configuration files you see in Xcode and floating around your Mac, are typically represented as XML, but did you know that any plist can be easily converted to JSON?
Any plist file can be converted to JSON using Apple's own plutil
command line utility. To use plutil, make sure you have downloaded the Xcode Command Line Tools.
To use the tool, locate the plist file you'd like to convert and then open a Terminal window and type:
plutil -convert json myplist.plist
That's all there is to it. You should now have a JSON file in place of the XML plist.
