# 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 =  
# 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."C:\Users\Vishesh\Desktop\demo.xlsx")
