Preparing data, having located it in Google (though only some) (7)
I believe the answer is:
editing
'preparing data' is the definition.
'located it in google though only some' is the wordplay.
'though only some' says the answer is hidden in the clue.
'EDITING' is hidden in the letters of 'located it in google'.
'having' is the link.
(Other definitions for editing that I've seen before include "Preparing for publication by correcting etc." , "revision" , "Changing" , "Preparing (text) for publication" , "Revising for publication" .)
