Why do you want to do this? In JavaScript it is normally unecessary to need to worry about the exact data type - it's possible you are trying to solve a problem which does not exist, which is why I'm asking.

Solution 1

get the json property and use typeof

C#

var json = { Col1: 1, Col2: 'text', Col3: null, Col4: true };
typeof (json.Col1); // number
typeof (json.Col2); // string
typeof (json.Col3); // object
typeof (json.Col4); // boolean
