        Do you mean the other way around? I.e., using unquoted keys? The
        JSON spec says that the keys must be quoted. The reason for this is
        that there is a bug in Javascript where it will treat a key as a
        keyword if it is unquoted and matches a keyword. Javascript is not
        smart enough to realize it should not be treating the key as a keyword.

            Somewhat smaller? I was thinking a large object would be shrunk by half
            because there would be no repetition of the columnnames everywhere. . ...

            And I thought my idea would make getting a value as easy as

            myJSON["js63009"].Company

            I suppose the list of columnnames could be an array since people would
            propbably make it into one so they can loop over it?
