Program Code – Python And Excel: Using Python for Excel Automation
import openpyxl
from openpyxl.styles import Font
# Open the Excel file or create it if does not exist
try:
wb = openpyxl.load_workbook('automation_test.xlsx')
except FileNotFoundError:
wb = openpyxl.Workbook()
# Select a sheet or create it if does not exist
sheet_name = 'Sheet1'
if sheet_name not in wb.sheetnames:
wb.create_sheet(title=sheet_name)
sheet = wb[sheet_name]
# Add some data with bold headers
headers = ['Name', 'Position', 'Department']
sheet.append(headers)
for col in range(1, len(headers)+1):
sheet.cell(row=1, column=col).font = Font(bold=True)
# A list of employee data to add to the sheet
employees = [
['John Doe', 'Developer', 'IT'],
['Jane Smith', 'Designer', 'Creative'],
['Dave Brown', 'Manager', 'HR']
]
# Add each employee's data to the sheet
for employee in employees:
sheet.append(employee)
# Save the updated spreadsheet
wb.save('automation_test.xlsx')
Code Output:
The code does not produce an output in the traditional sense as it is automating Excel operations; however, the expected result is an Excel file named ‘automation_test.xlsx’ with the following content:
- The first row will contain the headers ‘Name’, ‘Position’, ‘Department’, in bold.
- The following rows will contain the data for John Doe, Jane Smith, and Dave Brown with their respective positions and departments.
Code Explanation:
The program starts with importing the necessary modules from ‘openpyxl’, which is the Python library we’re using to automate Excel. It allows us to read, write, and modify Excel files.
At the outset, it attempts to open an existing Excel workbook called ‘automation_test.xlsx’. If the file doesn’t exist, it creates a new blank workbook.
The script then checks to see if ‘Sheet1’ exists. If not, it creates a new sheet with that name.
The headers for the Excel sheet are defined as a list and appended to the first row of the Excel sheet. A loop is used to make sure that these headers are bold by altering the font style.
An employees list is created, containing sublists with employee data.
Each sublist from the employees list is then appended as a row to the Excel sheet.
Finally, the changes are saved to ‘automation_test.xlsx’. This will either update the existing file or create a new one with the employee data and formatted headers.
The program is designed to be easy to extend. For instance, if you want to add more employees or change the data structure, you can simply update the ’employees’ list or modify the headers. It serves as a simple example of Python-Excel automation for common tasks like populating spreadsheets with data and basic formatting.
