Last Updated : 17 Sep, 2024

Openpyxl is a Python library for reading and writing Excel (with extension xlsx/xlsm/xltx/xltm) files. The Openpyxl Module allows Python programs to read and modify Excel files. For example, users might have to go through thousands of rows and pick out a few handfuls of information to make small changes based on some criteria. Using Openpyxl module, these tasks can be done very efficiently and easily.

Program to Print the Particular Cell Value

# import openpyxl module
import openpyxl

# Give the location of the file
path = "C:\\Users\\Admin\\Desktop\\demo.xlsx"

# To open the workbook 
# workbook object is created
wb_obj = openpyxl.load_workbook(path)

# Get workbook active sheet object
# from the active attribute
sheet_obj = wb_obj.active

# Cell objects also have a row, column, 
# and coordinate attributes that provide
# location information for the cell.

# Note: The first row or 
# column integer is 1, not 0.

# Cell object is created by using 
# sheet object's cell() method.
cell_obj = sheet_obj.cell(row = 1, column = 1)

# Print value of cell object 
# using the value attribute
print(cell_obj.value)

Output:

STUDENT 'S NAME

Determine Total Number of Rows

# import openpyxl module
import openpyxl

# Give the location of the file
path = "C:\\Users\\Admin\\Desktop\\demo.xlsx"

# to open the workbook
# workbook object is created
wb_obj = openpyxl.load_workbook(path)
sheet_obj = wb_obj.active

# print the total number of rows
print(sheet_obj.max_row)

Output

Determine Total Number of Columns

# importing openpyxl module
import openpyxl

# Give the location of the file
path = "C:\\Users\\Admin\\Desktop\\demo.xlsx"

# workbook object is created
wb_obj = openpyxl.load_workbook(path)

sheet_obj = wb_obj.active

# print total number of column
print(sheet_obj.max_column)

Output

Print all Columns Name

# importing openpyxl module
import openpyxl

# Give the location of the file
path = "C:\\Users\\Admin\\Desktop\\demo.xlsx"

# workbook object is created
wb_obj = openpyxl.load_workbook(path)

sheet_obj = wb_obj.active
max_col = sheet_obj.max_column

# Loop will print all columns name
for i in range(1, max_col + 1):
    cell_obj = sheet_obj.cell(row=1, column=i)
    print(cell_obj.value)

Output

STUDENT 'S NAME

Print first Column Value

# importing openpyxl module

# Give the location of the file
path = "C:\\Users\\Admin\\Desktop\\demo.xlsx"

# workbook object is created
wb_obj = openpyxl.load_workbook(path)

sheet_obj = wb_obj.active
m_row = sheet_obj.max_row

# Loop will print all values
# of first column
for i in range(1, m_row + 1):
    cell_obj = sheet_obj.cell(row=i, column=1)
    print(cell_obj.value)

Output:
