Openpyxl is a Python library for reading and writing Excel (with extension xlsx/xlsm/xltx/xltm) files. The openpyxl module allows Python program to read and modify Excel files.
For example, users might have to go through thousands of rows and pick out a few handful of information to make small changes based on some criteria. Using Openpyxl module, these tasks can be done very efficiently and easily.
Use this command to install openpyxl module :
sudo pip3 install openpyxl
Input file :
Code #1 : Program to print the particular cell value
Python3
# Python program to read an excel file# import openpyxl moduleimport openpyxl# Give the location of the filepath = "C:\\Users\\Admin\\Desktop\\demo.xlsx"# To open the workbook# workbook object is createdwb_obj = openpyxl.load_workbook(path)# Get workbook active sheet object# from the active attributesheet_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 attributeprint(cell_obj.value) |
Output :
