XlsxWriter object save as http response to create download in Django

Question

XlsxWriter object save as http response to create download in Django?

Answer 1

When it comes to Django, you can even do without the whole StringIO shenanigans. HttpResponse behaves just like a StringIO in that respect:

from django.http import HttpResponse
from xlsxwriter.workbook import Workbook

def your_view(request):
    # your view logic here

    # create the HttpResponse object ...
    response = HttpResponse(content_type='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet')
    response['Content-Disposition'] = "attachment; filename=test.xlsx"

    # .. and pass it into the XLSXWriter
    book = Workbook(response, {'in_memory': True})
    sheet = book.add_worksheet('test')       
    sheet.write(0, 0, 'Hello, world!')
    book.close()

    return response

Addendum: You need to specify {'in_memory': True} or you might get HttpResponse has no attribute seek(). Thanks @Jeb
