I have a tabular data which I need to export to csv without using any external plugin or api. I used the window.open
method passing the mime types but faced issues like below:
How to determine whether Microsoft Excel or Open Office is installed on the system using jquery
The code should be independent of the fact that what is being installed on the system i.e., openoffice or ms excel. I believe CSV is the format which can be expected to show in both the editors.
CODE
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/JavaScript">
$(document).ready(function(){
$("#btnExport").click(function(e) {
var msg = GetMimeTypes();
//OpenOffice
window.open('data:application/vnd.oasis.opendocument.spreadsheet,' + $('#dvData').html());
//MS-Excel
window.open('data:application/vnd.ms-excel,' + $('#dvData').html());
//CSV
window.open('data:application/csv,charset=utf-8,' + $('#dvData').html());
e.preventDefault();
});
});
function GetMimeTypes () {
var message = "";
// Internet Explorer supports the mimeTypes collection, but it is always empty
if (navigator.mimeTypes && navigator.mimeTypes.length > 0) {
var mimes = navigator.mimeTypes;
for (var i=0; i < mimes.length; i++) {
message += "<b>" + mimes[i].type + "</b> : " + mimes[i].description + "<br />";
}
}
else {
message = "Your browser does not support this ";
//sorry!
}
return ( message);
}
</script>
</head>

Errors:
CSV: Unrecognised over the browsers
ODS & Excel: is working but I am not able to find which one to generate when system is having an excel installed or openoffice installed?
IE version 8 : it is totally not working, opens in a new window and as below screenshot.
See below for an explanation.

rowDelim = '"\r\n"',

Now uses HTML5 Blob
and URL
as the preferred method with Data URI
as a fallback.
Other answers suggest window.navigator.msSaveBlob
; however, it is known to crash IE10/Window 7 and IE11/Windows 10. Whether it works using Microsoft Edge is dubious (see Microsoft Edge issue ticket #10396033).
Merely calling this in Microsoft's own Developer Tools / Console causes the browser to crash:
navigator.msSaveBlob(new Blob(["hello"], {type: "text/plain"}), "test.txt");
Four years after my first answer, new IE versions include IE10, IE11, and Edge. They all crash on a function that Microsoft invented (slow clap).
Add
navigator.msSaveBlob
support at your own risk.
Typically this would be performed using a server-side solution, but this is my attempt at a client-side solution. Simply dumping HTML as a Data URI
will not work, but is a helpful step. So:
window.open
approach would not work in Firefox, so I used <a href="{Data URI here}">
.<a>
tag's download
attribute, which only works in Firefox and Google Chrome. Since it is just an attribute, it degrades gracefully.About the "download" attribute, see these:
Browsers testing includes:
The CSV is exported correctly, but when imported into Excel, the character ü
is printed out as ä
. Excel interprets the value incorrectly.
Introduce var csv = '\ufeff';
and then Excel 2013+ interprets the values correctly.
If you need compatibility with Excel 2007, add UTF-8 prefixes at each data value. See also:
