Hello JavaScripters,

I'm trying to download a blob file with type xlsx (excel) in Safari. I did this:

obReader = new FileReader();
obReader.onload = function(e) {
    obdata = btoa(obReader.result);
    obDatauri = 'data:' + isbContentType + ';base64,' + obdata;
    window.location = obDatauri; 
};
obReader.readAsBinaryString(iobBLOB);

This code above downloads pdf and txt files but when I use to download an excel file it doesn't works.

The var iobBLOB has the blob and isbContentType has the Content-Type, I have been used this ones:

application/vnd.ms-excel
application/force-download
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

and others seen in here

The Blob files has this type:

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

Tested on a Macbook pro, Safari 9.03

Note: This code works on ChromeiOS and Safari (iPhone)

Thanks for the help!

`readAsBinaryString` is deprecated. Also why not just use `readAsDataURL`? – Musa Feb 25 '16 at 18:52
ok, thanks @Musa for that. But i'm updated now and it happends the same. Look the fileReader result is like this: `"data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;base64,..."` and it downloads but with no extension. – Es Noguera Mar 02 '16 at 17:43
@EsNoguera You wanted to reply to Musa, not me. – rmaddy Mar 02 '16 at 17:45
@rmaddy yes man, excuse me – Es Noguera Mar 02 '16 at 17:48
