How to use Python to Read Excel Files

Introduction

Microsoft Excel files are essential for storing and organizing important data in today's data-driven environment. Excel files can include financial data, sales data, or scientific research findings, and they are widely used in many different businesses.

Python has a robust library environment that makes it possible to read and manipulate Excel files with ease. This post will examine how to use Python to read Excel files.

We'll also look at how IronXL is a strong substitute for Python libraries in reading Excel files in C# in this post. We'll explore its features, usability, and performance advantages while showcasing its powers with useful code samples.

How to use Python to read Excel files

1. Bring in the required libraries.
2. To read the Excel file, utilize the function in the library.
3. If necessary, include extra parameters like the sheet name or range in addition to the file location.
4. Put the information into a variable.
5. Perform data processing or cleansing as an optional step.
6. Proceed to analyze or manipulate the data.

Pandas-Excel-Reader

A specialized library called Pandas-Excel-Reader was developed on top of Pandas and provides improved capabilities for reading Excel files. Like Pandas' built-in read_excel() function, it offers a high-level interface for extracting data from an Excel spreadsheet into Pandas DataFrames.

On the other hand, Pandas-Excel-Reader provides extra features including quicker data loading, enhanced support for big Excel files, and backward compatibility with previous Pandas versions.

Developers dealing with huge datasets or experiencing problems with speed while using the regular Pandas read_excel() method may find this package especially helpful.

PyExcelerate

PyExcelerate is a little Python module that produces Excel files quickly and with little memory use. Although PyExcelerate is primarily concerned with creating Excel files, it also has functions for reading Excel files.

PyExcelerate allows developers to import data into Python data structures, including lists and dictionaries, from pre-existing Excel files. PyExcelerate's focus on efficiency and speed makes it appropriate for activities involving quick Excel reading, such as data analysis or reporting.

Pandas-Excel-Writer

A companion library to Pandas, Pandas-Excel-Writer is made specifically for creating Excel files. Although exporting Pandas DataFrames to Excel is its primary function, Pandas-Excel-Writer also can read data from pre-existing Excel files.

Developers have flexibility and control over the data extraction process by using Pandas-Excel-Writer to extract data from certain worksheets or ranges inside Excel files.

Pandas-Excel-Writer's smooth interface with Pandas makes it easier to read and write Excel files, allowing developers to manage Excel files efficiently in Python applications.

XlTable

A lightweight Python library called XlTable focuses on usability and simplicity in its design for reading and modifying Excel tables. Developers may extract data, apply filters, and carry out basic actions on table data using this high-level interface for dealing with Excel tables.

Although XlTable lacks some of the feature-richness of certain other libraries, it provides an easy-to-use method for manipulating Excel tables, which makes it appropriate for basic Excel reading jobs or projects with little code overhead.

Python-Excel

Reading, writing, and modifying Excel documents are all possible with the help of Python-Excel, a feature-rich Python library for working with Excel files. Python-Excel offers a robust feature set for Excel file processing and data extraction, while not being as popular as some other libraries.

Python-Excel may be used by developers to create reports, extract data from Excel files, and carry out data analysis operations. Python-Excel provides developers looking for a complete solution for manipulating Excel files in Python with a powerful API and a wealth of documentation. It is a competitive option.

IronXL

IronXL is a feature-rich C# library for manipulating Excel files. IronXL, created by Iron Software, offers a comprehensive range of features for reading, editing, and modifying Excel documents programmatically.

IronXL offers developers a smooth experience for Excel-related activities by streamlining Excel interactions in C# with its user-friendly API and comprehensive documentation.

Features of IronXL

IronXL in C#: Reading Excel Data

Let's now look at a useful code sample that shows you how to use IronXL in C# to read Excel data. We'll go over how to open an Excel file that already exists, get worksheet data, and get values out of certain cells:

using IronXL;
class Program
{
    static void Main(string [] args)
    {
        // Specify the path to the xlsx file
        string filePath = "SampleData.xlsx";
        // Create a new WorkBook object
        WorkBook workBook = WorkBook.Load(filePath);
        // Get the first worksheet from the Excel file
        WorkSheet workSheet = workBook.WorkSheets.First();
        // Retrieve data from specific cells
        string cellA1 = workSheet ["A1"].Value.ToString();
        string cellB1 = workSheet ["B1"].Value.ToString();
        // Display the retrieved data
        Console.WriteLine("Value of cell A1: " + cellA1);
        Console.WriteLine("Value of cell B1: " + cellB1);
        // Close the workbook
        workBook.Close();
    }
}

using IronXL;
class Program
{
    static void Main(string [] args)
    {
        // Specify the path to the xlsx file
        string filePath = "SampleData.xlsx";
        // Create a new WorkBook object
        WorkBook workBook = WorkBook.Load(filePath);
        // Get the first worksheet from the Excel file
        WorkSheet workSheet = workBook.WorkSheets.First();
        // Retrieve data from specific cells
        string cellA1 = workSheet ["A1"].Value.ToString();
        string cellB1 = workSheet ["B1"].Value.ToString();
        // Display the retrieved data
        Console.WriteLine("Value of cell A1: " + cellA1);
        Console.WriteLine("Value of cell B1: " + cellB1);
        // Close the workbook
        workBook.Close();
    }
}

We begin by defining the path to the Excel file ("SampleData.xlsx") in this code sample. Next, we use IronXL's Load() function to construct a new WorkBook object and supply the file location as an input.

The first Excel sheet is then opened from the Excel file, and we use cell references (such as "A1" and "B2") to access certain cells. Lastly, we use the Console.WriteLine() function to display the data that we have retrieved from these cell values. We also use IronXL to read multiple Excel sheets.

For the above code example, we have created a new Excel workbook shown in the below image.

Below is the output generated from the above code. To know more about IronXL code refer here.
