#-Link-Snipped-# - Your question isn't very clear. Do you want to know how to update the remote JSON file? Is the file located on remote server? Or you simply wish to update the data that you've received?

I just want to update the Json file by using Javascript.
for eg. If the field of Phone number is change I need to call onchage() function to update in json

I do agree the question is pretty unclear, but anyway would still take a stab at it.
In general, you have such 'things' like a file located at server side.
Javascript(Referring to client side) can only pass a request to the server to manipulate to an extent where it passes the required data, and nothing beyond that.
Beyond this, you would require a sever side language to take care of the replacing logic (You can still use javascript if you have are using Node as your server).
Give us more information on these lines and we can help you out. It would be interesting to see what you have done until now. Lets make this interactive.

use onchange method to catch event and based on email address, you can identify the json object, modify it and you have the update json object, now you can convert that to JSON data string. to test your json data you can use <a href="https://jsonformatter.org" target="_blank" rel="nofollow noopener noreferrer">Best JSON Formatter and JSON Validator: Online JSON Formatter</a>
