You can perform various modifications to an Excel file using IronXL for Python, with operations such as data updates, content additions, cell formatting, and more. Let's look at a few typical situations and how IronXL for Python can be used to resolve them. By the sample data that are going to be processed.
Updating current data is one of the most frequent activities involved in modifying Excel files using the below code. With IronXL for Python, you can easily write data in Excel xlsx files by adding new data, fixing errors, and updating out-of-date information.
from ironxl import *
# Load an existing Excel file
workbook = WorkBook.Load("output.xlsx")
# Access a specific worksheet
worksheet = workbook.WorkSheets[0]
# Update data in a specific cell
worksheet["B2"].Value = "29"
# Save the modified workbook
workbook.SaveAs("modified_data.xlsx")
From the above code, we load an existing Excel file, then open a particular worksheet, and manipulate data changes into the value of the cell ("A1"). The updated workbook is then saved as a new file.
Adding new rows, columns, or worksheets to Excel files is another feature that IronXL for Python offers. The following code shows adding a sample dataset to the existing file.
from ironxl import *
# Load an existing Excel file
workbook = WorkBook.Load("output.xlsx")
# Access a specific worksheet
worksheet = workbook.WorkSheets[0]
# new data
New_content=["Kent",25,55000]
rowcount=worksheet.RowCount+1
for index,Item in enumerate(New_content):
worksheet.SetCellValue(rowcount, (index), str(Item));
# Save the modified workbook
workbook.SaveAs("modified_data.xlsx")
In this example, we update an existing spreadsheet by adding new data as a new row at the specified location (i.e., row 5).
Another common chore when working with Excel files is formatting cells. For cell formatting, IronXL for Python offers comprehensive support, allowing you to adjust font styles, colors, borders, and alignment, and convert data into the desired format.
from ironxl import *
# Load an existing Excel file
workbook = WorkBook.Load("output.xlsx")
# Access a specific worksheet
worksheet = workbook.WorkSheets[0]
# Get the cell
cell = worksheet["B2"]
# Set background color of the cell with an RGB string
cell.Style.SetBackgroundColor("#428D65")
# Save the workbook
workbook.SaveAs("modified_data.xlsx")
In the above code, we format cell "B2" by setting a yellow background color and making the font bold.
