Introduction
Manipulating Excel files in Python can be challenging, especially when you are dealing with large datasets. In this article, we will explore the best techniques for opening and handling Excel files in Python using the Pandas library. We will cover everything from reading Excel files to filtering and grouping data, and provide plenty of coding examples to help you get started.
Why use Pandas?
Pandas is one of the most popular data manipulation libraries in Python, and for good reason. It offers a powerful set of tools for working with tabular data, making it the perfect tool for handling Excel files. With Pandas, you can quickly and easily manipulate large datasets and perform complex operations on them.
Reading Excel files with Pandas
The first step in working with Excel files in Python is to read in the data. Pandas makes this easy with its read_excel() function. This function reads in an Excel file and returns a DataFrame object, which you can then manipulate using Pandas’ built-in functions.
Example: Reading an Excel file with Pandas
| Excel File | Code | Result |
|---|---|---|
| excel_file.xlsx | df = pd.read_excel(‘excel_file.xlsx’) | A DataFrame containing the data in excel_file.xlsx |
Filtering and Sorting Data
Once you have read in your Excel file, you may want to filter or sort the data based on certain criteria. Pandas makes this easy with its built-in filtering and sorting functions.
Filtering Data
The simplest way to filter data in Pandas is to use boolean indexing. Boolean indexing allows you to filter a DataFrame based on a condition, such as selecting only the rows where a certain column meets a certain criteria.
Example: Filtering Data based on a Condition
| DataFrame | Code | Result |
|---|---|---|
| A DataFrame containing sales data | df[df[‘sales’] > 100] | A DataFrame containing only the rows where sales are greater than 100 |
Sorting Data
Pandas also makes it easy to sort data based on one or more columns. To sort a DataFrame, you can use the sort_values() function.
Example: Sorting Data based on a Column
| DataFrame | Code | Result |
|---|---|---|
| A DataFrame containing sales data | df.sort_values(‘sales’) | A DataFrame sorted by sales in ascending order |
Grouping Data
Grouping data in Pandas allows you to group rows based on values in one or more columns, and then apply a function to each group. This can be useful for quickly summarizing large datasets or creating subsets of data based on specific criteria.
Example: Grouping Data based on a Column
| DataFrame | Code | Result |
|---|---|---|
| A DataFrame containing sales data | df.groupby(‘region’)[‘sales’].sum() | A new DataFrame showing the total sales for each region |
Formatting Data
Excel files often contain formatting, such as bold text, borders, and cell colors. Pandas can preserve this formatting when reading in an Excel file, making it easy to convert your data to a well-formatted HTML or PDF document.
Example: Converting a DataFrame to an HTML Table with Formatting
| Excel File | Code | Result |
|---|---|---|
| A DataFrame containing sales data | df.to_html(index=False,border=0) | A well-formatted HTML table |
Conclusion
Working with Excel files in Python can seem daunting, but with the help of Pandas, it’s quick and easy to open, manipulate, and format your data. We’ve covered some of the most useful techniques, including filtering, sorting, grouping, and formatting data, and provided plenty of coding examples to help you started.

The most popular Python library for working with Excel files is openpyxl. Other libraries that can be used include xlsxwriter, pandas, and xlrd.
You can install openpyxl library by using pip command. In your command prompt, type:
pip install openpyxl
You can open an Excel file in Python using the load_workbook function from the openpyxl library. For example:
from openpyxl import load_workbook
workbook = load_workbook(filename=’example.xlsx’)
You can read data from an Excel file in Python using the worksheet function from the openpyxl library. For example:
from openpyxl import load_workbook
workbook = load_workbook(filename=’example.xlsx’)
worksheet = workbook[‘Sheet1’]
cell_value = worksheet[‘A1’].value
You can write data to an Excel file in Python using the worksheet function from the openpyxl library. For example:
from openpyxl import load_workbook
workbook = load_workbook(filename=’example.xlsx’)
worksheet = workbook[‘Sheet1’]
worksheet[‘A1’] = ‘Hello World’
workbook.save(filename=’example.xlsx’)
You can manipulate data in an Excel file in Python using the worksheet function from the openpyxl library. For example:
from openpyxl import load_workbook
workbook = load_workbook(filename=’example.xlsx’)
worksheet = workbook[‘Sheet1’]
cell_value = worksheet[‘A1’].value
worksheet[‘B1’] = cell_value.upper()
workbook.save(filename=’example.xlsx’)
