Want to convert plist to text

I want to convert plist to text because I accidently deleted Sticky widget and want to get the text back (via Time machine) then just create a document with the information.

I need something non techinical - I googled it but was not easy to find a simple solution. I tried downloading Apple developer tools but took so long I cancelled the down load. I tried an internet convertor but the file was blank. I know it is not as I can see the actualy text but failing all this I will edit the file manually but that is tedious work.

Thank you.
