Excel files are ubiquitous in data analysis and manipulation tasks, offering a convenient way to store and organize tabular data. In Python, there are multiple libraries available for reading Excel files, each with its own set of features and capabilities. Two prominent options are Pandas and IronXL, both offering efficient methods for reading Excel files in Python.
In this article, we'll compare the functionality and performance of Pandas and IronXL to Read Excel files in Python.
Pandas is a powerful open-source data analysis and manipulation library for Python. It introduces the DataFrame data structure, which is a two-dimensional labeled data structure with columns of potentially different types. Pandas offers a wide range of functionalities for data manipulation, including reading and writing data from various sources, such as CSV files, SQL databases, and Excel files.
Some key features of Pandas include:
Pandas introduces the DataFrame data structure, which is essentially a two-dimensional labeled data structure with columns of potentially different types. It's similar to a spreadsheet or SQL table, making it easy to perform operations like filtering, grouping, and aggregation on tabular data.
Pandas offers a wide range of functions for data manipulation, including merging, reshaping, slicing, indexing, and pivoting data. These operations allow users to clean, transform, and prepare data for analysis or visualization efficiently.
Pandas provides robust support for working with time series data, including tools for date/time indexing and resampling, and convenient methods for handling missing data and time zone conversion.
Pandas can seamlessly collaborate with various Python libraries frequently employed in data analysis and scientific computations, including NumPy, Matplotlib, and Scikit-learn. This interoperability allows users to leverage the strengths of different libraries within a single analysis workflow.
Overall, Pandas is a powerful tool for data manipulation and analysis in Python, and it's widely used in various domains, including finance, economics, biology, and social sciences.
IronXL is a Python library designed specifically for working with Excel files. It provides an intuitive API for reading, writing, and manipulating Excel documents in Python. IronXL aims to simplify Excel file operations by offering a straightforward interface and eliminating the need for external dependencies, such as Microsoft Excel or Excel Interop.
Some key features of IronXL are listed below:
IronXL offers a Python 3+ Excel document API that's intuitive and easy to use, allowing developers to seamlessly read, edit, and create Excel spreadsheet files.
Designed for Python 3+ and compatible with Windows, Mac, Linux, and cloud platforms, IronXL ensures flexibility in deployment environments.
Developers can work with Excel files in Python without installing Microsoft Office or dealing with Excel Interop, simplifying the integration process and minimizing dependencies.
Supports Python 3.7+ on various operating systems including Microsoft Windows, macOS, Linux, Docker, Azure, and AWS. Compatible with popular IDEs like JetBrains PyCharm and other Python IDEs.
Create, load, save, and export spreadsheets in various formats including XLS, XLSX, XSLT, XLSM, CSV, TSV, JSON, HTML, Binary, and Byte Array.
Edit metadata, set permissions and passwords, create and remove worksheets, manipulate sheet layout, handle images, and more.
Perform various operations on cell ranges such as sorting, trimming, clearing, copying, finding and replacing values, setting hyperlinks, and merging and unmerging cells.
Customize cell styles including font, size, border, alignment, and background pattern, and apply conditional formatting.
Utilize math functions like average, sum, min, and max, and set cell data formats including text, number, formula, date, currency, scientific, time, boolean, and custom formats.
First of all, Python needs to be installed on your machine. Install the latest version of Python 3.x from the official Python website. When installing Python, ensure you choose the option to add Python to the system PATH, allowing access from the command line.
To demonstrate the functionality of both Pandas and IronXL in reading Excel files, let's create a Python project using PyCharm, a popular integrated development environment (IDE) for Python.
Open PyCharm and create a new Python project.
Configure the Project as follows:
To install Pandas in your Project, you can follow these steps:
Open Command Prompt or Terminal: In PyCharm, from View->Tool Windows->Terminal.
Install Pandas via pip: Pandas can be installed using the pip package manager. Run the following command in the terminal:
pip install pandas
pip install pandas
This command installs the Pandas library and its dependencies from the Python Package Index (PyPI).
Install OpenPyXL via pip: OpenPyXL is the library that helps read and write Excel files. It is one of the dependencies used by Pandas. When you install Pandas, OpenPyXL is automatically installed if not present already. If somehow it isn't installed, then you can install it using the following command in the terminal:
pip install openpyxl
pip install openpyxl
To install IronXL in a Python project, follow these steps:
Ensure Prerequisites: Before installing IronXL, make sure you have the necessary prerequisites installed on your system.
.NET 6.0 SDK: IronXL relies on the IronXL .NET library, specifically .NET 6.0, as its underlying technology. Ensure that you have the .NET 6.0 SDK installed on your machine. You can download it from the official .NET website.
Install IronXL via pip: IronXL can be installed using the pip package manager. Run the following command:
:ProductInstall
W```
This command will collect, download, and install the IronXL library and its dependencies from the Python Package Index (PyPI).

:ProductInstall
W```
This command will collect, download, and install the IronXL library and its dependencies from the Python Package Index (PyPI).

As we have set up everything, we'll move on to reading Excel files using both libraries. The demo Excel file that we are going to read has the following values with header rows as Name, Marks, and Res:
Import the Pandas library and use the read_excel() function to read column data from the Excel file.
import pandas as pd
# Read the Excel file
df = pd.read_excel("file.xlsx")
import pandas as pd
# Read the Excel file
df = pd.read_excel("file.xlsx")
When using Pandas' read_excel() function, you can specify several options for displaying as required:
index_col: Specifies which column or columns to use as the index of the DataFrame. You can pass a single column name or column index, or you can pass a list of column names or column indices to create a MultiIndex.
converters: Specifies functions to apply to columns for custom parsing. You can pass a dictionary where keys are column names or column indices and values are functions.
These options provide flexibility when reading Excel files with Pandas, allowing you to customize the reading process according to your specific requirements.
Display the contents of the DataFrame.
print(df)
print(df)
Here is the output of the above code:
Step 1: Import the IronXL library and use the WorkBook.Load() method to load the Excel file. In the Load method parameter, you can pass the valid file URL, local file path object, or filename if it is in the same directory as the script.
from ironxl import WorkBook
# Load the Excel file as a WorkBook object
workbook = WorkBook.Load("file.xlsx")
from ironxl import WorkBook
# Load the Excel file as a WorkBook object
workbook = WorkBook.Load("file.xlsx")
Step 2: With IronXL, you can access multiple sheets and print column labels. Access the worksheets and cells to read the column-stored data. The cells can be of any data type like numeric columns or string columns. The cell values can be converted to int by parsing string columns to numeric values using the IntValue property and vice versa.
# Access the first worksheet
worksheet = workbook.DefaultWorkSheet
# Select a specific cell and return the converted value
cell_value = worksheet["A2"].IntValue
print(cell_value)
# Read from the entire worksheet and print each cell's address and value
for cell in worksheet:
print(f"Cell {cell.AddressString} has value '{cell.Text}'")
# Access the first worksheet
worksheet = workbook.DefaultWorkSheet
# Select a specific cell and return the converted value
cell_value = worksheet["A2"].IntValue
print(cell_value)
# Read from the entire worksheet and print each cell's address and value
for cell in worksheet:
print(f"Cell {cell.AddressString} has value '{cell.Text}'")
Here is the output of the above code with a proper display format showcasing the versatility of IronXL:
