How to generate xlsx file from Django model

As you may have guessed, my reporting project is entirely focused on helpdesk events recording. At the end of the month, the system administrator must submit a report in the xlsx format for business head. To create such files, we need openpyxl.

from openpyxl import Workbook
from openpyxl.styles import PatternFill, Border, Side, Alignment, Protection, Font

@login_required
def saveinfo(request, username):
#function receives username as argument for filtering data in the model. 
#Don't forget add correct path in urls.py such as path
#('saveinfo/<str:username>', views.saveinfo, name='saveinfo'),
# and generate links for this in template.
    """
    Downloads all infos as Excel file with a single worksheet
    """
    try:
        if username == 'all':
            saveinfo = Addinfo.objects.order_by('date_added')
        else:
            saveinfo = Addinfo.objects.filter(work_user=username).order_by('date_added')
    except:
        username = request.user.id
        saveinfo = Addinfo.objects.filter(work_user=username).order_by('date_added')
