Write a workbook

wb = Workbook()

dest_filename = 'empty_book.xlsx'

ws1 = wb.active

ws1.title = "range names"

for row in range(1, 40):

ws1.append(range(600))

ws2 = wb.create_sheet(title="Pi")

ws2['F5'] = 3.14

ws3 = wb.create_sheet(title="Data")

for row in range(10, 20):

for col in range(27, 54):

ws3.cell(column=col, row=row, value="{0}".format(get_column_letter(col)))

print(ws3['AA10'].value)

wb.save(filename = dest_filename)

output 

Read an existing workbook

from openpyxl import load_workbook

wb = load_workbook(filename = 'empty_book.xlsx')

sheet_ranges = wb['range names']

print(sheet_ranges['D18'].value)

output 

>>> 3

Using formulae

from openpyxl import Workbook

wb = Workbook()

ws = wb.active

# add a simple formula

ws["A1"] = "=SUM(5, 4)"

wb.save("formula.xlsx")
