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:
