search the phone number of users from json file data

I have to make a project where I've to display the phone number of the user provided in the text box. The JSON file is in my local machine.
sample data is below:

// user_phone
var family = [{
"name" : "Harry",
"Phone" : "67854639"
},
{
"name" : "Kyle",
"Phone" : "670074639"
}];

The application should be like this, when supplied name the phone number should be displayed.

Name:  Harry
Phone: 67854639
