Python - Writing to an excel file using openpyxl module
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, user might have to go through thousands of rows and pick out few handful information to make small changes based on some criteria. Using Openpyxl module, these tasks can be done very efficiently and easily.
Example
# import openpyxl module
import openpyxl
#Call a Workbook() func of openpyxl to create a new blank Workbook object
wb = openpyxl.Workbook()
# Get workbook active sheet from the active attribute
sheet = wb.active
# Cell objects also have row, column and coordinate attributes that provide
# location information for the cell.
# The first row or column integer is 1, not 0. Cell object is created by
# using sheet object's cell() method.
c1 = sheet.cell(row = 1, column = 1)
# writing values to cells
c1.value = "Vishesh"
c2 = sheet.cell(row= 1 , column = 2)
c2.value = "Ved"
#Once have a Worksheet object,one can access a cell object by its name also
# A2 means column = 1 & row = 2.
c3 = sheet['A2']
c3.value = "Python"
# B2 means column = 2 & row = 2.
c4 = sheet['B2']
c4.value = "Programming"
#Anytime you modify the Workbook object or its sheets and cells, the #spreadsheet file will not be saved until you call the #save()workbook method.
wb.save("C:\\Users\\Vishesh\\Desktop\\demo.xlsx")
