Wrong encoding?

[divined]

let xhr = new XMLHttpRequest();
xhr.open('GET', 'http://domain.com/some.xlsx', true);

xhr.onload = function(e) {
  if (this.status === 200) {
    fileDownload(this.response, 'export.xlsx', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
  }
};

xhr.send();

File downloaded, but wrong encoded, file opens as text inside xlsx -(

Anybody found a solution?

I solved some problem after add
xhr.responseType = 'blob';

[Kenneth Jiang]

Cool! Can you open a PR for that @fred-kruger ? Thank you so much!

maybe this is not the missing part about this library, just set responseType option in native xhr or related xhr library(eg: axios) to blob can solve this problem.

for sake of other people met the same problem, maybe just add troubleshooting section in README and linked to current issue is OK.

I've added something to the README to help people avoid this gotcha.
