Python Library to Use Excel in Python
For working with Excel files in Python, we will use Aspose.Cells for Python, a powerful library that provides extensive capabilities for creating, modifying, and converting Excel files.
Please download the package or install it from PyPI using the following pip command in your terminal:
pip install aspose-cells-python
Use Excel in Python: Reading Excel Files
In automating excel with python, reading Excel files is a powerful and flexible way to handle data programmatically in your applications. You can start working with an Excel file by loading it into your Python script. Load an Excel file by creating an instance of the Workbook class with the file path of the Excel file you wish to read. After loading the Excel file, you can access its individual worksheets by their index or by their name. The worksheets collection of the Workbook class object allows you to navigate through the different sheets within the Excel file.
Please follow the steps below to read an Excel file in Python:
- Load the Excel file using the Workbook class.
- Get the length of the WorksheetCollection using the Workbook.worksheets.length property.
- Loop through all the worksheets in the collection and do the following:
- Access the worksheet by its index using the worksheets.get() method.
- Get a count of data rows and columns in the worksheet.
- Start a loop for rows.
- Start a nested loop for columns.
- Read data from each cell using the Worksheet.cells.get_cell(row, column).value property.
The following code sample shows how to read an Excel file in Python.

Use Excel in Python: Writing to Excel Files
You can easily create new Excel files programmatically in Python using Aspose.Cells for Python. The first step is to create a new Workbook class object that will serve as the container for your Excel file. A new workbook typically starts with one default worksheet. You can access this worksheet by its index or by name. With the worksheet object ready, you can start writing data to specific cells. Cells are referenced using their cell addresses (e.g., “A1” and “B2”). You can write various types of data, including strings, numbers, dates, and Booleans.
Please follow the steps below to create an Excel file in Python:
- Create an instance of the Workbook class.
- Access the default worksheet using the Workbook.worksheets().get(index) method.
- Input the value in the desired cell using the Worksheet.cells.get(index).value property.
- Save the workbook as an XLSX file using the Workbook.save() method.
The following code sample shows how to create an Excel file and insert data into it using Python.

Use Excel in Python: Modifying Excel Files
Modifying existing Excel files with Aspose.Cells for Python involves several key tasks, including loading the file, making changes to its structure and content, and saving the updated file. If you want to modify an existing file, you can load it into a Workbook class object. The Workbook class provides methods to open and handle various Excel file formats, such as XLSX, XLS, and CSV. You can access a specific worksheet to make modifications to its content or structure. You can also add more worksheets by name or by using the index. With the worksheet object ready, you can modify the values of specific cells. You can change the existing data in these cells to new values.
Please follow the steps below to modify an Excel file in Python:
- Load an existing Excel file using the Workbook class.
- Access the default worksheet using the Workbook.worksheets().get(index) method.
- Modify the values in the desired cells using Worksheet.cells.get(index).value property.
- Add a new sheet using the Workbook.worksheets.add(name) method.
- Input values in the desired cells using the Worksheet.cells.get(index).value property.
- Save the workbook using the Workbook.save() method.
The following code sample shows how to edit an Excel file in Python.
