Setup Environment

Prerequisites

Make sure you have the following installed on your PC before beginning the tutorial:

  • .NET 6.0 SDK: Because IronXL is designed with the .NET 6.0 SDK, your machine must have this installed.
  • Python 3.0+: This tutorial assumes that you have installed Python 3.0 or a later version.
  • pip: Install pip first, the Python package installer, since IronXL will require it.

Install IronXL

Open Visual Studio Code and create a Python file named ReadSpreadsheet.py. This file will contain our script for reading Excel files with IronXL.

Installing the library is the first step to take before utilizing IronXL. Using Python's package manager pip, you can quickly install IronXL by running the following command:

pip install ironxl
pip install ironxl
SHELL

Now that IronXL is installed, you may use its Excel spreadsheet file reading capabilities.

Reading Excel spreadsheet

IronXL makes it easy to conduct data analysis in an Excel spreadsheet. To begin, let us import data from a pre-existing Excel sheet file format into our Python environment:

from ironxl import *     # Import IronXL library for Excel operations

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

# Access the default worksheet (usually the first one)
worksheet = workbook.DefaultWorkSheet

# Access a specific cell value
cell_value = worksheet["A1"].StringValue

# Access row values as a string
row_values = worksheet.Rows[1].StringValue

# Access column values as a string
column_values = worksheet.Columns[0].StringValue

# Iterate over all rows and print their values
for row in worksheet.Rows:
    print(row.StringValue)
from ironxl import *     # Import IronXL library for Excel operations

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

# Access the default worksheet (usually the first one)
worksheet = workbook.DefaultWorkSheet

# Access a specific cell value
cell_value = worksheet["A1"].StringValue

# Access row values as a string
row_values = worksheet.Rows[1].StringValue

# Access column values as a string
column_values = worksheet.Columns[0].StringValue

# Iterate over all rows and print their values
for row in worksheet.Rows:
    print(row.StringValue)
PYTHON

We use the location of our Excel file to instantiate the WorkBook class after importing it from IronXL. In doing so, we generate a workbook object that we can use to access and retrieve the spreadsheet's contents. Once we've loaded it into a workbook object, we can access the Excel spreadsheet's data, including cell values, rows, and columns stored in the object. IronXL Excel workbooks additionally offer simple ways to make and get data from multiple Excel sheets.

We can obtain the value of a single cell (e.g., A1), as well as tabular data such as the values of a specific row, column labels, and a list of column names. Working with data often involves looping through the rows and columns of an Excel spreadsheet. IronXL simplifies this process with its handy iteration techniques. We can easily process and manipulate the data contained within the Excel sheet by iterating over each row, column index, and cell.
