Step 1: Import the IronXL Library
Import IronXL using the Python package manager for reading Excel spreadsheet data.
pip install ironxl
pip install ironxl
Next, import the necessary libraries from IronXL:
from ironxl import License, WorkBook, WorkSheet
from ironxl import License, WorkBook, WorkSheet
Step 2: Add License Key
IronXL needs 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"
Step 3: Load the Excel File
Load the Excel file using the WorkBook.Load()
function. This method returns a Workbook object, which represents the entire Excel file.
# Load the workbook
workbook = WorkBook.Load('sample.xlsx')
# Load the workbook
workbook = WorkBook.Load('sample.xlsx')
Step 4: Read Excel Files Using IronXL
Now use the workbook object to read the sheets and then read the data in the sheets.
# Iterate over all worksheets
for sheet in workbook.WorkSheets:
print(f"Sheet Name: {sheet.Name}")
for row in sheet.Rows:
# Print each row's values
print([cell.Value for cell in row]) # excel data
# Iterate over all worksheets
for sheet in workbook.WorkSheets:
print(f"Sheet Name: {sheet.Name}")
for row in sheet.Rows:
# Print each row's values
print([cell.Value for cell in row]) # excel data
Complete Code
Input Excel File
from ironxl import License, WorkBook, WorkSheet
# Set the IronXL license key
License.LicenseKey = "Your Key"
# Load the Excel workbook
workbook = WorkBook.Load('sample.xlsx')
# Iterate through the sheets in the workbook
for sheet in workbook.WorkSheets:
# Print the name of each sheet
print(f"Sheet Name: {sheet.Name}")
# Iterate through the rows in the current sheet
for row in sheet.Rows:
# Print each row's values as a list
print([cell.Value for cell in row])
from ironxl import License, WorkBook, WorkSheet
# Set the IronXL license key
License.LicenseKey = "Your Key"
# Load the Excel workbook
workbook = WorkBook.Load('sample.xlsx')
# Iterate through the sheets in the workbook
for sheet in workbook.WorkSheets:
# Print the name of each sheet
print(f"Sheet Name: {sheet.Name}")
# Iterate through the rows in the current sheet
for row in sheet.Rows:
# Print each row's values as a list
print([cell.Value for cell in row])
Code Explanation
The provided code demonstrates how to use IronXL to read data from an Excel file with multiple sheets. Here's an explanation of the code step by step:
1. License Key Setup
The first line of the code sets up the IronXL license by specifying the license key using the License.LicenseKey
property. This is required for activating the IronXL library and ensuring it can be used without restrictions.
2. Loading the Excel Workbook
The second line uses the WorkBook.Load()
method to load an Excel file (sample.xlsx
) into a WorkBook
object. This object represents the entire workbook (i.e., the Excel file) and contains all the sheets and data within the file.
3. Iterating Through Sheets
The code then begins a loop through the sheets in the workbook. The WorkBook.WorkSheets
property gives access to all the sheets in the loaded workbook. For each sheet, it prints the name of the sheet using sheet.Name
. This is useful for identifying which sheet is being processed, especially when working with multiple sheets.
4. Reading and Printing Data from Each Sheet
Within each sheet, the code loops through each row using sheet.Rows
. Each row is a collection of cells in that specific row. The code then extracts the value of each cell in the row using cell.Value
, and prints it as a list for each row.
Output
IronXL License (Trial Available)
IronXL works on a valid license key in the code. Users can easily get a trial license from the license page. To use the license, place the license somewhere in the code as shown below before using the IronXL library.
ironxl.License.LicenseKey = "Your License Key"
ironxl.License.LicenseKey = "Your License Key"
