How to iterate through Excel rows in Python?

In this article, we are going to discuss how to iterate through Excel Rows in Python. In order to perform this task, we will be using the Openpyxl module in python. Openpyxl is a Python library for reading and writing Excel (with extension xlsx/xlsm/xltx/xltm) files. The openpyxl module allows a Python program to read and modify Excel files.

We will be using this excel worksheet in the below examples:

Approach #1:

We will create an object of openpyxl, and then we’ll iterate through all rows from top to bottom.

Python3

# import module
import openpyxl

# load excel with its path
wrkbk = openpyxl.load_workbook("Book1.xlsx")

sh = wrkbk.active

# iterate through excel and display data
for i in range(1, sh.max_row+1):
    print("\n")
    print("Row ", i, " data :")

    for j in range(1, sh.max_column+1):
        cell_obj = sh.cell(row=i, column=j)
        print(cell_obj.value, end=" ")

Output:

Approach #2

We will create an object of openpyxl, and then we’ll iterate through all rows using iter_rows() method.

Python3

# import module
import openpyxl

# load excel with its path
wrkbk = openpyxl.load_workbook("Book1.xlsx")

sh = wrkbk.active

# iterate through excel and display data
for row in sh.iter_rows(min_row=1, min_col=1, max_row=12, max_col=3):
    for cell in row:
        print(cell.value, end=" ")
    print()

Output:
