You don't have to export a file using the Excel format in order to get the data into Excel. It is generally much easier to export to CSV. CSV files should be associated with Excel by default, so it should have the Excel icon by it and everything. XML would work the same way, I think, but the CSV format is much lighter, and does the same job in this case. Converting JSON to CSV is simple:

var response = JSON.parse(responseJSON).response;
var csv = arrayToCSV(response);

function arrayToCSV(arr) {
    var columnNames = [];
    var rows = [];
    for (var i=0, len=arr.length; i<len; i++) {
        // Each obj represents a row in the table
        var obj = arr[i];
        // row will collect data from obj
        var row = [];
        for (var key in obj) {
            // Don't iterate through prototype stuff
            if (!obj.hasOwnProperty(key)) continue;
            // Collect the column names only once
            if (i === 0) columnNames.push(prepareValueForCSV(key));
            // Collect the data
            row.push(prepareValueForCSV(obj[key]));
        }
        // Push each row to the main collection as csv string
        rows.push(row.join(','));
    }
    // Put the columnNames at the beginning of all the rows
    rows.unshift(columnNames.join(','));
    // Return the csv string
    return rows.join('\n');
}

// This function allows us to have commas, line breaks, and double 
// quotes in our value without breaking CSV format.
function prepareValueForCSV(val) {
    val = '' + val;
    // Escape quotes to avoid ending the value prematurely.
    val = val.replace(/"/g, '""');
    return '"' + val + '"';
}

I have a jqGrid where I get data at once from server (java) in JSON format. I want the data in the jqGrid to be exported into Excel format.

Here's a nice article, showing you how to export from jqGrid to Excel...

I solved this like this:

1. Read

https://w3lessons.info/2015/07/13/export-html-table-to-excel-csv-json-pdf-png-using-jquery/#Installation

2. Here is github

https://github.com/kayalshri/tableExport.jquery.plugin

3. Here is a demo

http://demos.w3lessons.info/jquery-table-export#

It works perfectly i tried the Export Excel. In my case i just used the id selector for the jqgrid table.

BTW This will export only visible part so if you 100 pages it need server side because info is just not there !.
