IRONXL FOR PYTHON の使用方法

複数のシートを持つ Excel ファイルを Python で読む方法

In Python, handling Microsoft Excel files is a common task, especially in data analysis, report generation, and automation workflows. Traditionally, libraries like openpyxl or pandas are used to manipulate Excel files. However, a lesser-known but powerful library called IronXL is gaining attention due to its robust capabilities and ease of use when working with Excel files in Python.

IronXL, a .NET-based library, enables reading and writing Excel files with various features such as handling multiple sheets, complex formatting, and supporting different Excel file formats. In this article, we’ll explore how to use IronXL Python to read Excel files with multiple sheets and demonstrate some of its key features and functionalities.

Introduction to IronXL

IronXL for Python is a robust library designed to work with Microsoft Excel files. It allows developers to create, read, and manipulate Excel spreadsheets seamlessly. The main advantages of using IronXL include its ease of use, powerful functionalities, and the fact that it does not require Microsoft Excel to be installed on the server. Developers can read multiple files in an Excel file with ease.

How to Read Excel Files in Python with Multiple Sheets

Step 1: Import the IronXL Library.

Step 2: Add License Key.

Step 3: Load the Excel File.

Step 4: Accessing Sheets in the Workbook.

Why Use IronXL?

IronXL is ideal for various applications such as data analysis, reporting, and automation. Its intuitive API and comprehensive features make it a popular choice among developers. Some of the key features of IronXL include:

  • No Dependency on Microsoft Excel: IronXL does not require Microsoft Excel to be installed, making it suitable for server environments.
  • Support for Multiple Formats: It supports XLS files, XLSX files, and CSV file formats.
  • Cross-Platform Compatibility: IronXL works on Windows, macOS, Linux, Docker, Azure, and AWS.
  • Ease of Integration: With a natural and intuitive API, IronXL can be easily integrated into any Python project.

Step 1: Import the IronXL Library

Import IronXL using:

from ironxl import License, WorkBook, WorkSheet
from ironxl import License, WorkBook, WorkSheet
PYTHON

Step 2: Add License Key

IronXL works with a license key. Get your free license from here and place the license at the top of the code.

License.LicenseKey = "Your Key"
License.LicenseKey = "Your Key"
PYTHON

Step 3: Load the Excel File

You can load the Excel file using the WorkBook.Load() function. This method returns a Workbook object, representing the entire Excel file.

workbook = WorkBook.Load('sample.xlsx')
workbook = WorkBook.Load('sample.xlsx')
PYTHON

Step 4: Accessing Sheets in the Workbook

Once the workbook is loaded, you can access individual sheets. IronXL allows you to access sheets by name or index. Let’s assume your Excel file has multiple sheets.

To access all sheets in the workbook, you can iterate through them:

# Get sheet names from the workbook
sheet_names = workbook.WorkSheetsNames
print("Sheet Names:", sheet_names)

# Iterate through each sheet and read its contents
for sheet in workbook.WorkSheets:
    print(f"Sheet Name: {sheet.Name}")  # Access specific sheet
    for row in sheet.Rows:
        print([cell.Value for cell in row])  # Print each row's cell values
# Get sheet names from the workbook
sheet_names = workbook.WorkSheetsNames
print("Sheet Names:", sheet_names)

# Iterate through each sheet and read its contents
for sheet in workbook.WorkSheets:
    print(f"Sheet Name: {sheet.Name}")  # Access specific sheet
    for row in sheet.Rows:
        print([cell.Value for cell in row])  # Print each row's cell values
PYTHON

Advanced Features of IronXL

In addition to reading and writing data, IronXL comes with many advanced features that allow you to manipulate Excel files more effectively:

  • Cell Formatting: IronXL enables you to format cells with different styles, fonts, colors, and number formats.
  • Handling Different Excel Formats: It supports .xlsx, .xls, and .csv formats.
  • Performance: IronXL is optimized for high performance, making it suitable for working with large Excel files.
  • Write Data Back to Excel: Besides reading data, you can also modify and save changes to Excel files using IronXL.

Input Excel file

The Excel file has two sheets:

Full Code Example

To read all the sheets: Here's the complete code to read an Excel file with multiple sheets:

from ironxl import License, WorkBook, WorkSheet

# Set your IronXL license key
License.LicenseKey = "Your License Key"

# Load the Excel workbook
workbook = WorkBook.Load('sample.xlsx')

# Read Multiple Sheets
for sheet in workbook.WorkSheets:
    print(f"Sheet Name: {sheet.Name}")
    for row in sheet.Rows:
        print([cell.Value for cell in row])  # Print each row values
from ironxl import License, WorkBook, WorkSheet

# Set your IronXL license key
License.LicenseKey = "Your License Key"

# Load the Excel workbook
workbook = WorkBook.Load('sample.xlsx')

# Read Multiple Sheets
for sheet in workbook.WorkSheets:
    print(f"Sheet Name: {sheet.Name}")
    for row in sheet.Rows:
        print([cell.Value for cell in row])  # Print each row values
PYTHON

Code Explanation

  • Importing Libraries: It imports WorkBook and WorkSheet classes from the IronXL library, which are used to work with Excel files and sheets, respectively.
  • Loading the Excel Workbook: The Load() method is used to open the Excel file sample.xlsx and load it into a workbook object.
  • Iterating through Multiple Sheets: The code loops through all sheets in the workbook using the WorkSheets property. For each sheet, it prints the sheet's name.
  • Reading Rows in Each Sheet: For each sheet, it iterates through the rows and prints the values of each cell in that row as a list. The Value property of each cell is used to retrieve the content.
