I have json data which needs to be exported to an excel sheet. I have tried
window.open('data:application/vnd.ms-excel,' + encodeURIComponent( $('#tableId').html()));
But this works for html table only.
$(document).ready(function() {
$('button').click(function() {
var data = $('#txt').val();
if (data == '')
return;
JSONToCSVConvertor(data, "Vehicle Report", true);
});
});
function JSONToCSVConvertor(JSONData, ReportTitle, ShowLabel) {
//If JSONData is not an object then JSON.parse will parse the JSON string in an Object
var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;
var CSV = '';
//Set Report title in first row or line
CSV += ReportTitle + '\r\n\n';
//This condition will generate the Label/Header
if (ShowLabel) {
var row = "";
//This loop will extract the label from 1st index of on array
for (var index in arrData[0]) {
//Now convert each value to string and comma-seprated
row += index + ',';
}
row = row.slice(0, -1);
//append Label row with line break
CSV += row + '\r\n';
}
//1st loop is to extract each row
for (var i = 0; i < arrData.length; i++) {
var row = "";
//2nd loop will extract each column and convert it in string comma-seprated
for (var index in arrData[i]) {
row += '"' + arrData[i][index] + '",';
}
row.slice(0, row.length - 1);
//add a line break after each row
CSV += row + '\r\n';
}
if (CSV == '') {
alert("Invalid data");
return;
}
//Generate a file name
var fileName = "MyReport_";
//this will remove the blank-spaces from the title and replace it with an underscore
fileName += ReportTitle.replace(/ /g, "_");
//Initialize file format you want csv or xls
var uri = 'data:text/csv;charset=utf-8,' + escape(CSV);
// Now the little tricky part.
// you can use either>> window.open(uri);
// but this will not work in some browsers
// or you will not get the correct file extension
//this trick will generate a temp <a /> tag
var link = document.createElement("a");
link.href = uri;
//set the visibility hidden so it will not effect on your web-layout
link.style = "visibility:hidden";
link.download = fileName + ".csv";
//this part will append the anchor tag and remove it after automatic click
document.body.appendChild(link);
link.click();
document.body.removeChild(link);

this solution works fine with large JSON data, IE error issues, hope this will help
$(document).ready(function() {
$("#button1").on('click', function(e) {
var url = "";
$.ajax({
type: "GET",
url: url,
success: function(result) {
DownloadJsonData(result, "NewFile", true);
},
error: function(result) {
alert('Error ');
}
});
});
function DownloadJsonData(JSONData, FileTitle, ShowLabel) {
//If JSONData is not an object then JSON.parse will parse the JSON string in an Object
var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;
var CSV = '';
//This condition will generate the Label/Header
if (ShowLabel) {
var row = "";
//This loop will extract the label from 1st index of on array
for (var index in arrData[0]) {
//Now convert each value to string and comma-seprated
row += index + ',';
}
row = row.slice(0, -1);
//append Label row with line break
CSV += row + '\r\n';
}
//1st loop is to extract each row
for (var i = 0; i < arrData.length; i++) {
var row = "";
//2nd loop will extract each column and convert it in string comma-seprated
for (var index in arrData[i]) {
row += '"' + arrData[i][index] + '",';
}
row.slice(0, row.length - 1);
//add a line break after each row
CSV += row + '\r\n';
}
if (CSV == '') {
alert("Invalid data");
return;
}
//Generate a file name
var filename = FileTitle + (new Date());
var blob = new Blob([CSV], {
type: 'text/csv;charset=utf-8;'
});
if (navigator.msSaveBlob) { // IE 10+
navigator.msSaveBlob(blob, filename);
} else {
var link = document.createElement("a");
if (link.download !== undefined) { // feature detection
// Browsers that support HTML5 download attribute
var url = URL.createObjectURL(blob);
link.setAttribute("href", url);
link.style = "visibility:hidden";
link.download = filename + ".csv";
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
}

If the csv format fits your need, then it can be easily done like in this topic.
Otherwise, you will have to parse manually your JSON to the 'XML' format of a Excel file (because I don't know any library doing this). In this case, you will have to study the Excel file format, which is explained in this MSDN blog.
