In this post we will be creating a Python script that will apply a double accounting underline to a cell within an existing Excel spreadsheet using the openpyxl library. Openpyxl is a library that allows us to interact with Excel files in Python. It provides a range of tools for reading, writing, manipulating, and formatting Excel data. This makes it a useful tool for data analysis and reporting tasks.
See the sample of Python code below where we use the openpyxl library to apply a double accounting underline to cells within an already existing Excel spreadsheet. We start by loading our existing Excel file called
example.xlsx and assign it to a variable named
workbook. Next we retrieve the active worksheet from the workbook. We then select cell
A1 of the
worksheet and assign it to the variable
cell. Now we create a
Font object with the
underline property set to
Font.UNDERLINE_DOUBLE_ACCOUNTING. This is then assigned to the
font property of our
cell. Finally the changes made to the Excel file are saved using the
import openpyxl from openpyxl.styles import Font workbook = openpyxl.load_workbook('example.xlsx') worksheet = workbook.active cell = worksheet['A1'] cell.font = Font(underline=Font.UNDERLINE_DOUBLE_ACCOUNTING) workbook.save('example.xlsx')
