• pip: Since IronXL will be installed via pip, make sure pip, the Python package installer, is installed.

Setting Up Your Environment

1. Creating a File in Visual Studio Code

Launch Visual Studio Code, then create the ParseExcel.py Python file. This file will include our IronXL script for reading Excel files.

2. Installing IronXL

In Visual Studio Code, choose Terminal > New Terminal from the menu to launch the command line.

To install IronXL, execute the subsequent command:

pip install ironxl

pip install ironxl

Parse Excel files using IronXL

The process to read excel files is made easy with the help of the IronXL library. Parsing Excel files in python can be easily done with a few lines of code.

from ironxl import *     workbook = WorkBook.Load("Demo.xlsx")
worksheet = workbook.WorkSheets [0]  # Accessing the first worksheet
for row in range(worksheet.RowCount):
    for col in range(worksheet.ColumnCount):
        cell_value = worksheet.Columns [col].Rows [row].Value
        print(cell_value)
workbook.Close()

from ironxl import *     workbook = WorkBook.Load("Demo.xlsx")
worksheet = workbook.WorkSheets [0]  # Accessing the first worksheet
for row in range(worksheet.RowCount):
    for col in range(worksheet.ColumnCount):
        cell_value = worksheet.Columns [col].Rows [row].Value
        print(cell_value)
workbook.Close()

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'from ironxl import * workbook = WorkBook.Load("Demo.xlsx") worksheet = workbook.WorkSheets [0] # Accessing the first worksheet for row in range(worksheet.RowCount): for col in range(worksheet.ColumnCount): cell_value = worksheet.Columns [col].Rows [row].Value print(cell_value) workbook.Close()

Importing the required IronXL modules into your script is the first step. Next, use the WorkBook class in IronXL to import Excel files. The path of your Excel file should be used instead of "Demo.xlsx" or we can use a different type of file format like CSV file, XLS, and xlsx file formats. We can access an individual Excel sheet inside the workbook once the Excel file has loaded using the WorkBook.Load() method. The IronXL library also allows us to access multiple Excel sheets by using the index or sheet names.

Next, we extract data from the Excel file by iterating over rows and columns while having access to the worksheet. This little piece of code prints the value of each spreadsheet cell as it iterates over them. This logic can be adjusted to meet your unique needs, such as gathering data for additional processing or examination. It is imperative that you close the Excel file using the workbook.Close() method once you have completed processing it in order to free up system resources.
