How to add color to Excel cells using Python
The openpyxl Python library provides various different modules to read and modify Excel files. Using this module, we can work on the Excel workbooks very easily and efficiently. In this section, we will discuss how we can add the background color to Excel cells in Python using the openpyxl library.
Program to add color to Excel cells in Python
Note: Before starting programming, create an Excel file with some data, or you can choose any of your existing Excel files.
Step1: Import the openpyxl Library and modules to the Python program for adding color to the cell.
import openpyxl from openpyxl.styles import PatternFill
Note: openpyxl.styles provides various different functions that style your cells in many different ways, like changing the color, font, alignment, border, etc.
Step2: Connect/Link your Excel workbook file and corresponding workbook’s working Sheet with the Python Program.
wb = openpyxl.load_workbook("//home//codespeedy//Documents//MyWorkBook.xlsx") #path to the Excel file ws = wb['Sheet1'] #Name of the working sheet
Step3: Call the PaternFill() function with the Pattern type and foreground color parameters of your choice.
fill_cell = PatternFill(patternType='solid', fgColor='C64747') #You can give the hex code for different color
Step4: Lastly, fill the cell with color by using the name of the particular cell of the working sheet, and save the changes to the workbook.
ws['B2'].fill = fill_cell # B2 is the name of the cell to be fill with color wb.save("//home//codespeedy//Documents//MyWorkBook.xlsx")
Here is the complete Python Program:
import openpyxl from openpyxl.styles import PatternFill wb = openpyxl.load_workbook("//home//codespeedy//Documents//MyWorkBook.xlsx") ws = wb['Sheet1'] #Name of the working sheet fill_cell1 = PatternFill(patternType='solid', fgColor='FC2C03') fill_cell2 = PatternFill(patternType='solid', fgColor='03FCF4') fill_cell3 = PatternFill(patternType='solid', fgColor='35FC03') fill_cell4 = PatternFill(patternType='solid', fgColor='FCBA03') ws['B2'].fill = fill_cell1 ws['B3'].fill = fill_cell2 ws['B4'].fill = fill_cell3 ws['B5'].fill = fill_cell4 wb.save("//home//sanamsahoo0876//Documents//MyWorkBook.xlsx")
Now, close the Excel application and reopen it to see the changes.
