Introduction

Excel files are widely used to store and manipulate data. Some common tasks in Excel sheets usage include storing sales data and automating the calculation of sales forecast. However, manual manipulation can be laborious and prone to error when incorporating this data into your Python scripts. A common library that is often used with python when dealing with large data set is the usage of pandas library. However users needs to import pandas along with other dependences which would make it less than ideal in terms of scalability. Moreover the learning curve of panada is steep and its API is daunting for a beginner as such, this is where the robust Python module IronXL comes in, which makes working with Excel files easier.

This post teaches you how to read Excel files in Python using Visual Studio code. We will discuss advanced methods for effective data processing, go over the installation procedure, and examine key code examples for reading different data structures.

How to read an Excel file in Python using Visual Studio Code

  1. Create a new Project/ environment for Python using Visual Studio code.
  2. Install IronXL library for Python.
  3. Import the library into the Python code.
  4. Import the Excel file to be read.
  5. Select the worksheet and get the value using range or cell address.
  6. Process the value and display the result.

Select a place on your PC where you wish to save your newly created project folder. To create the project folder, click "Select Folder".

Creating a Python File in VS Code

You can create a new Python file in the newly created project folder, which will contain your Python code.

There are two methods to do this:

  • Right-click anywhere in the project folder and choose New File. Name your Python file (say, my_script.py) after the .py extension.
  • Navigate to File > New File (or use Ctrl+N on Windows/Linux or Cmd+N on macOS to open a new file). Press Enter after naming your Python file with the .py extension.

Install IronXL

In Visual Studio Code, select Terminal > New Terminal to open a terminal window.

To install IronXL, use the pip package manager:

 pip install IronXL

Read Excel file Using IronXL

Reading Excel files can easily done by using IronXL with few lines of code. Let's start by creating the code necessary to obtain data stored from an Excel workbook and open it.

from ironxl import *
workbook = WorkBook.Load("Demo.xlsx")
worksheet = workbook.WorkSheets [0]
for cell in worksheet ["A2:A10"]:
    print("Cell {} has value '{}'".format(cell.AddressString, cell.Text))
PYTHON

Importing the IronXL library gives us access to all of its features. Then, we load the Microsoft Excel file that the user wishes to work with using ironxl.open_workbook function. The path to your Excel workbooks can be passed as a parameter in this example we are passing a .xlsx file. We can also pass CSV files as a parameter. Since Worksheets in Excel files can have more than one sheet, IronXL offers methods for gaining access to and utilizing multiple sheets.

Next, we take out multiple Excel sheets from the workbook using the worksheet name or access the Excel sheet by index if you don't know the names of the worksheets. Depending on your requirements, IronXL provides a variety of data access options. From the sheet, we can get the Excel range from A2 to A10. We can then use a for loop, to display the values one by one.
