number1 number2 number3
12         23      45
23         44      47
34         67      88

Answer 1

If you dont want to use pandas then you can just use write function of xlsxwriter:

import xlsxwriter

l1=[[12,23,45],[23,44,47],[34,67,88]]

workbook = xlsxwriter.Workbook('temp.xlsx')
worksheet = workbook.add_worksheet()

row = 0
for i in range(len(l1[0])):
    worksheet.write(row, i, "number"+str(i+1))
row += 1
for items in (l1):
    for i in range(len(items)):
        worksheet.write(row, i, items[i])
    row += 1
workbook.close()
