Answer 1

class QueryToExcel(object):
def __init__(self, doc_name = 'doc_name'):
    #some set up stuff
    self.b_io = BytesIO()
    self.workbook = pd.ExcelWriter(self.b_io, engine='xlsxwriter')
    self.run() #fill in workbook with pandas dataframes
    self.workbook.save()

def get_workbook(self):
    return self.b_io.getvalue()


app = Flask(__name__)
app.debug = True 
@app.route('/pvh/', methods = ['GET'])
def get_workbook(self):
    return self.b_io.getvalue()
