How to merge multiple Excel files using Python

In today's data-driven landscape, consolidating information scattered across multiple Excel files is a common challenge. Fortunately, Python provides powerful tools to streamline this process, offering a more efficient way to merge and organize data. In this guide, we'll explore how to leverage Python's capabilities to effortlessly combine multiple Excel files into a cohesive and structured dataset.

In the world of data, things get messy when you have multiple Excel files with the same columns. If you're looking to tidy up and merge them all into one file, especially when you need to go through them one by one, you're in the right place. This guide will show you an easy way to make sense of it all and keep your data organized.

Python Solution

Merge multiple Excel files effortlessly with this Python code! 🚀 Using pandas and os, the script navigates through files in a specified folder, combining them into a neat merged_excel.xlsx file. Just plug in your folder path, run the code, and voila – streamlined data! 📊💻

# import packages
import pandas as pd
import os

# Define a function 'append' to merge Excel files in a specified path
def append(path):
    # Create an empty list to store individual DataFrames    
	frames = []    
	for root, dirs, files in os.walk(path):        
		for file in files:            
			file_with_path = os.path.join(root, file)          
			df = pd.read_excel(file_with_path)      
			frames.append(df)    
	df = pd.concat(frames, axis=0)    
	return df

# path：The folder path where storage all the excel files 
df = append(path) 
df.to_excel("merged_excel.xlsx")

In this code snippet, we're using two powerful tools: pandas and os (a module for working with the operating system).

The append function is the star here. It digs through all the Excel files in a specified folder ('path') and collects them into a DataFrame, which is like a neat table for our data.

Now, for the magic moment: the last two lines! They use our append function to merge all the Excel data in the specified folder into one consolidated file called merged_excel.xlsx.
