var xhr = new XMLHttpRequest();
xhr.open('GET', 'path/to/your/file.json', true);
xhr.onreadystatechange = function() {
    if (xhr.readyState === 4 && xhr.status === 200) {
        var data = JSON.parse(xhr.responseText);
        console.log(data);
    }
};
xhr.send();

fetch('path/to/your/file.json')
    .then(response => response.json())
    .then(data => console.log(data))
    .catch(error => console.error('Error:', error));

<input type="file" id="jsonFileInput">

document.getElementById('jsonFileInput').addEventListener('change', function(event) {
    var file = event.target.files[0];
    if (file) {
        var reader = new FileReader();
        reader.onload = function(e) {
            var contents = e.target.result;
            var data = JSON.parse(contents);
            console.log(data);
        };
        reader.readAsText(file);
