Python: Split Each Excel Sheet Into Separate Files (fast & easy)
Introduction
Splitting worksheets from a single Excel workbook into separate files can streamline data management, especially when dealing with large datasets. In this post, I’ll walk you through the process of using Python and the xlwings library to accomplish this task efficiently.
Getting Started with xlwings
Before diving into the code, ensure you have the xlwings library installed. If you haven’t installed it yet, you can do so by running the following command in your terminal:
pip install xlwings
Setting Up Your Python Script
Once you have xlwings ready, you can start by creating a new Python script. The first step is to import the library:
import xlwings as xwNext, you need to specify the Excel file you want to split. If the file is in the same directory as your script, you only need to provide the file name. If not, make sure to include the full path:
EXCEL_FILE = 'YOUR_EXCEL_FILE.xlsx'Creating a New Excel Instance
To manipulate the Excel file, I’ll create a new instance of Excel:
app = xw.App(visible=False)Setting visible=False ensures that the Excel window does not pop up during execution, keeping the process smooth and unobtrusive.
Opening the Excel File and Iterating Through Worksheets
Now, let’s open the specified Excel file and iterate through each worksheet:
wb = app.books.open(EXCEL_FILE)Within the workbook, I’ll loop through each sheet, copying it into a new workbook.
After saving each new workbook, it’s crucial to close it to free up memory. Here’s how the workflow looks:
Running the Script
Once everything is set up, save your script and execute it to see the results. You should now have a separate workbook for each worksheet in your original Excel file.
Conclusion
By using Python and the xlwings library, I’ve shown you how to efficiently split each worksheet in an Excel workbook into separate files. This method not only saves time but also minimizes potential errors associated with manual copying and pasting.
