Setup Environment


Before starting the guide, confirm that the following are installed on your computer:

  • IronXL requires the .NET 6.0 SDK to be installed on your computer because it was built using it.
  • Python 3.0+: You must have Python 3.0 or a later version installed to follow this tutorial.
  • pip: Since IronXL will need the Python package installer pip, install it first.

Install IronXL

Make a Python file named after opening this file in Visual Studio Code. Our script for using IronXL to export Excel files is contained in this file.

Export Data To Excel using IronXL

With IronXL Python, exporting data to a new or existing Excel file without the need to import Pandas is simple. Let's examine a straightforward illustration of data exporting to an Excel spreadsheet:

from ironxl import *     data = [
    ["Name", "Age", "Salary"],
    ["John", 30, 50000],
    ["Alice", 25, 60000],
    ["Bob", 35, 70000]
# Create new Excel WorkBook document
workbook = WorkBook.Create()
# Create a blank WorkSheet
worksheet = workbook.CreateWorkSheet("new_sheet")
# Write data to Excel worksheet
for row_idx, row_data in enumerate(data):
    for col_idx, cell_data in enumerate(row_data):
            worksheet.SetCellValue(row_idx, (col_idx), str(cell_data));
        except Exception as e:
            print("An exception occurred"+str(e))
# Save the workbook to the ExcelWriter object file path

A sample dataset is created in the code snippet above as a list of lists that represent data rows and columns. Then, we use nested loops to write each data frame to a new Excel worksheet of an existing file we created using IronXL's CreateWorkSheet method and by passing the Excel sheet name as a parameter. like this we can able to create multiple sheets. The output target file name can be saved as "output.xlsx". Which creates a new Excel file on the location.

Customizing the Excel Export

# Customizing Excel export
worksheet["A1"].Style.Font.Bold = True
 worksheet["A1"].Style.BackgroundColor = "Red"
worksheet.Columns[0].Width = "20"
 worksheet.Columns[0].FormatString = "$#,###0.00"
# Save the workbook

Without using any additional Python libraries installed, we may change the look of the produced Excel spreadsheet in this example by bolding the font, changing the background color of cell row A1 to yellow, modifying column B's width, and formatting column C as currency. IronXL can able to handle missing data representation in the Excel spreadsheet. To learn more about IronXL's code, check here.
