Read JSON Object

HI all,

I need to read the file in which the data is in JSON format but i need remove the spaces and newlines from the uploaded file.

Please suggest the required.

The following is the code snippet

               var r = new FileReader(); 

                    r.onload = function(e)

                    { 

                    var fileContent = e.target.result;

                    var val=fileContent.replace(/ /g,"");

                       }

File format

[{"country": "Nepal",

"value": 260

},

      {"country": "Bhutan","value": 700}]

Thanks

mano
