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 *

# Load the workbook
workbook = WorkBook.Load("Demo.xlsx")

# Accessing the first worksheet
worksheet = workbook.WorkSheets[0]

# Iterate over each row and column
for row in range(worksheet.RowCount):
    for col in range(worksheet.ColumnCount):
        # Get the value of each cell
        cell_value = worksheet.Columns[col].Rows[row].Value
        print(cell_value)

# Close the workbook to free up system resources
workbook.Close()
from ironxl import *

# Load the workbook
workbook = WorkBook.Load("Demo.xlsx")

# Accessing the first worksheet
worksheet = workbook.WorkSheets[0]

# Iterate over each row and column
for row in range(worksheet.RowCount):
    for col in range(worksheet.ColumnCount):
        # Get the value of each cell
        cell_value = worksheet.Columns[col].Rows[row].Value
        print(cell_value)

# Close the workbook to free up system resources
workbook.Close()
PYTHON

The first step is to import the required IronXL modules into your script. Next, use the WorkBook class in IronXL to import Excel files. Replace "Demo.xlsx" with the path to your Excel file, or use a different file format like CSV, XLS, or XLSX. You can access individual Excel sheets inside the workbook once the Excel file has loaded using the WorkBook.Load() method. The IronXL library also allows access to multiple Excel sheets using the index or sheet names.

Next, we extract data from the Excel file by iterating over rows and columns while accessing the worksheet. This 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 to close the Excel file using the workbook.Close() method once you have completed processing it in order to free up system resources.
