Python Program to Merge Excel Cells using openpyxl

In this article, we will discuss how to merge cells in an excel sheet using Python. We will use openpyxl module for merging cells.

Installation of openpyxl using pip

pip install openpyxl

Implementation Of Merging Cells using openpyxl

Openpyxl provides a merge_cells() function for merging cells. When we merge cells, the top cell will be deleted from the worksheet. Openpyxl also provides an unmerged_cells() method for separating cells.

Syntax

merge_cells(range_string=None, start_row=None, start_column=None, end_row=None, end_column=None)

# import library
from openpyxl import Workbook  
from openpyxl.styles import Alignment  

work_book = Workbook()  
work_sheet = work_book.active  
  
# cells to merge  
work_sheet.merge_cells('A1:D3')  
  
cell = work_sheet.cell(row=1, column=1)  
# value of cell
cell.value = 'quick fox jumps over the lazy dog'  
# aligment of data in cell
cell.alignment = Alignment(horizontal='center', vertical='center')  
  
# save the workbook  
work_book.save('Excel_merge_cell.xlsx')
