Hi junaid,
I understood your issues your first issue is an encoding issue for which you just need to update "csvEncoding" in that code and add "%EF%BB%BF" which will solve your first issue, now about your second issue it is due to an usual behavior of csv files, which displays large numbers in that exponential value,For a workaround to solve that you need to append '\u200C' character to specifically to your mobile number field or you can add '\u200C' (as it is an empty character so it will not effect any value, it will just display them as string) character to all your fields if you want to display them all as string. so after making these updates your code will be updated as follows.

@namespace Converts JSON to CSV.
Compress with:
(function (window) {
"use strict";
Default constructor
var _CSV = function (JSONData) {
if (typeof JSONData === 'undefined')

var csvData = typeof JSONData != 'object' ? JSON.parse(settings.JSONData) : JSONData,
csvEncoding = 'data:text/csv;charset=utf-8,%EF%BB%BF',
csvOutput = "",
csvRows = [],
BREAK = '\r\n',
FILENAME = "export.csv";

// Get and Write the headers
csvHeaders = Object.keys(csvData[0]);
csvOutput += csvHeaders.join(',') + BREAK;

for (var i = 0; i < csvData.length; i++) {
var rowElements = [];
for(var k = 0; k < csvHeaders.length; k++) {
rowElements.push('\u200C' +csvData[i][csvHeaders[k]]);
} // Write the row array based on the headers
csvOutput += csvRows.join(BREAK);
// Initiate Download
var a = document.createElement("a");

if (navigator.msSaveBlob) { // IE10
navigator.msSaveBlob(new Blob([csvOutput], { type: "text/csv" }), FILENAME);
} else if ('download' in a) { //html5 A[download]
a.href = csvEncoding + encodeURIComponent(csvOutput); = FILENAME;
setTimeout(function() {;
}, 66);
} else if (document.execCommand) { // Other version of IE
var oWin ="about:blank", "_blank");
oWin.document.execCommand('SaveAs', true, FILENAME);
} else {
alert("Support for your specific browser hasn't been created yet, please check back later.");
window.CSVExport = _CSV;
