Try this
**Html**
<input id="file" type="file" />
<p>Select a file with the following format.</p>
<pre>
{
"Userinfo":{
"name": "Mohan",
"interest": "C,Html,Go"
}
}
</pre>
**Js**
(function(){
function onChange(event) {
var reader = new FileReader();
reader.onload = onReaderLoad;
reader.readAsText(event.target.files[0]);
}
function onReaderLoad(event){
console.log(event.target.result);
var obj = JSON.parse(event.target.result);
document.querySelector(".infos").innerHTML=`name:${obj.Userinfo.name}interest: ${obj.Userinfo.interest}`
}
document.getElementById('file').addEventListener('change', onChange);
}());

Create the page but set it's display to none.
Then add the window element.style.display="block" in the onChange function

I found how to open a new window with json content!
Javscript code:
let newwindow=window.open("","Dynamic Popup");
newwindow.write(`
<style>
#out{
box-shadow:5px 0px 8px grey;
border-radius:5%;
height: auto;
position:relative;
top:100px;
}
.infos{
position:relative;
left:25%;
top:20%;
font-weight:bolder;
padding:2%;
width:50%;
box-shadow:2px 0px 5px grey;
background-color:whitesmoke;
}
g{
background-color:lightgreen;
color:red;
}
</style>
<body>
<div id="out">
<br/>
<div class="infos">
<g>Name</g> : ${obj.Userinfo.name}
</div>
<br/>
<div class="infos">
<g>Interest</g> : ${obj.Userinfo.interests}
</div>
<br/>
</div>
</body>
`);

1. You can try 'accept' attribute to accept json file
accept="application/JSON"
Note : it can overridden by users
[ Accept attributes - https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/accept ]
2. To get data U can use 'FileReader'
[ FileReader - https://developer.mozilla.org/en-US/docs/Web/API/FileReader ]

Change the "data.json" to the json file path and try again

How you will give data.json?
That file will be only uploaded by the user. So that the file has different name.

Create the json file first

I already created the HTML code(and json file contains user informations) in my pc. And the code will accept the json file I don't know how to retrieve the data from it and open a new page contains the data.

Try accessing it like this
async function load() {
var ud = await fetch("data.json")
ud=ud.json()
document.querySelectorAll(".infos")[0].innerHTML=ud.userinfo.name;
}
window.onload=()=>{
load()
}
