A little update on @alecxe response for Python 3 (io.BytesIO instead of StringIO.StringIO) and Django >= 1.5 (content_type instead of mimetype), with the fully in-memory file assembly that has since been implemented by @jmcnamara ({'in_memory': True}) !
Here is the full example :

import io

from django.http.response import HttpResponse

from xlsxwriter.workbook import Workbook


def your_view(request):

    output = io.BytesIO()

    workbook = Workbook(output, {'in_memory': True})
    worksheet = workbook.add_worksheet()
    worksheet.write(0, 0, 'Hello, world!')
    workbook.close()

    output.seek(0)

    response = HttpResponse(output.read(), content_type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")
    response['Content-Disposition'] = "attachment; filename=test.xlsx"

    output.close()

    return response
