How to Combine Multiple Excel Sheets into One File Using Python

Are you dealing with numerous Excel files and sheets that you need to consolidate into a single document? This task can become tedious if done manually, especially if you want to maintain the original names of the sheets and ensure all your data stays intact. Fortunately, with Python and the Pandas library, this process can be automated smoothly, saving you time and effort. In this guide, we’ll walk you through a complete guide on how to combine multiple Excel sheets from various files into one single Excel file while keeping everything as it is.

The Problem: Merging Sheets from Multiple Excel Files

Imagine you have two workbooks, Workbook1 and Workbook2, with multiple sheets each:

Workbook1

Sheet1

Sheet2

Sheet3

Workbook2

Sheet11

Sheet22

You wish to compile these into a single workbook named FinalWorkbook that contains all the sheets from both workbooks without any changes to the data. The manual method of copying and pasting is not feasible for multiple documents, which is where automation becomes essential.

Solution: Using Python to Merge Sheets

What You'll Need

To execute this task, you'll need the following:

Python installed on your system

pandas and openpyxl libraries installed. You can install them using pip if you haven't done so already:

Step-by-Step Guide

Here’s how to combine all sheets from multiple Excel files into one file step-by-step:

1. Setup Your Python Environment

Make sure your working directory contains the Excel files you want to combine. Create a new folder named Combined where the final consolidated file will be stored.

2. Write the Code

Here is the complete code to achieve this:

3. Execute the Code

Save the script and run it in your terminal or command prompt. The code will:

Create a new Excel file named combined_file.xlsx.

Loop through each Excel file in your directory.

For each sheet in these files, it will read and append the data into the combined file.

Finally, it will clean up by removing any temporary sheets that were created during the process.

Conclusion

By following these simple steps, you can quickly consolidate multiple Excel sheets from various workbooks into a single file, preserving all your data and sheet names. This method not only saves you time but also reduces the risk of human error associated with manual copying and pasting. Anyone working with large datasets will find this tool invaluable in streamlining their data management tasks.

Happy coding!
