In this section, we are going to append values in Excel. For that, we are going to use the append() method. We can add a group of values at the bottom of the current sheet in which we want to put the values. Create a script called append_values.py and write the following content in it:

from openpyxl import Workbook 

book_obj = Workbook()
excel_sheet = book_obj.active
rows = (
    (11, 12, 13),
    (21, 22, 23),
    (31, 32, 33),
    (41, 42, 43)
)
for values in rows:
    excel_sheet.append(values)
    print()

print("values are successfully appended")
book_obj.save('test.xlsx')wb.save('append_values.xlsx')

Run the script and you will get the following output:

student@ubuntu:~/work$ python3 append_values.py

Following is the output:

values are successfully appended

In the preceding example, we appended three columns of data in the append_values.xlsx files sheet. The data we stored was in a tuple of tuples and to append that data we went through the container row by row and inserted it using the append() method.
