Why Unmerge Cells in Excel?
Merging cells can help with formatting and creating headers, but it often creates issues when sorting, filtering, or applying formulas. Unmerging cells restores individual cell functionality, making your data more manageable. Here are some reasons why you might need to unmerge cells:
- Sorting & Filtering: Merged cells can interfere with sorting and filtering operations.

- Consistent Layout: Unmerging cells ensures uniform row and column sizes, especially for printing.
How to Unmerge Cells in Excel?
Unmerging cells in Excel can be done in several ways, depending on your needs. Below, we'll guide you through each method step by step and help you find a method that suits your needs.
Unmerge Cells Using the Merge & Center Button
The quickest and most straightforward way to unmerge cells in Excel is through the Merge & Center button on the Home tab. This method is ideal for occasional tasks where you need to unmerge a few cells quickly. Follow these steps to unmerge your cells:

Select All Merged Cells: Press Ctrl + A to select all results from the list, then close the Find dialog.
-
Unmerge the Cells: Use any of the previously described methods to unmerge all selected cells simultaneously.
This approach is highly efficient for cleaning up large datasets or preparing Excel files for analysis.
Unmerge Cells Using VBA
VBA (Visual Basic for Applications) allows users to automate the unmerging process, especially for repetitive tasks or handling multiple worksheets. If you frequently need to unmerge cells across different sheets, VBA is an excellent choice.
Here's a simple VBA script to unmerge all cells in a specific worksheet:
Sub UnmergeAllCells()
Dim ws As Worksheet
Set ws = ThisWorkbook.Sheets("Sheet1") ' Replace with your sheet name
' Loop through all the merged cells and unmerge them
Dim cell As Range
For Each cell In ws.UsedRange
If cell.MergeCells Then
cell.UnMerge
End If
Next cell
End Sub
Steps to Use the VBA Script:
- Open the Excel workbook and press Alt + F11 to open the Visual Basic for Applications editor.
- Insert a new module by clicking Insert > Module.
- Paste the script above into the module window.
- Press F5 to run the macro to unmerge all cells in the worksheet.
For more details about the UnMerge method used in this VBA script, please check the official documentation from Microsoft: Range.UnMerge method (Excel).
Unmerge Cells Using Python
If you prefer not to use Excel or VBA, Python offers a flexible solution for unmerging cells programmatically. By leveraging libraries like Spire.XLS for Python, you can easily create, edit, and manipulate Excel files - including merging and splitting cells - without needing Microsoft Excel.
Here's an example of how you can unmerge cells in Excel using Python:
-
Install Spire.XLS:
First, install the Spire.XLS for Python library from PyPI by running the following command:
pip install spire-xls -
Write the Python Script to unmerge cells:
Once you have the library installed, you can write a Python script to unmerge all cells in an Excel worksheet. Here's a simple example:
from spire.xls import * # Load the Excel file workbook = Workbook() workbook.LoadFromFile("your_file.xlsx") # Replace with your file path # Get the first worksheet sheet = workbook.Worksheets[0] # Get all merged cells ranges = sheet.MergedCells # Loop through each merged range and unmerge for cell in ranges: cell.UnMerge() # Save the modified workbook workbook.SaveToFile("unmerged_file.xlsx", ExcelVersion.Version2013) # Save to a new file workbook.Dispose() # Clean up the resources -
Run the Script:
After writing the script, simply execute it. The script will unmerge all merged cells in the first worksheet and save the changes in a new Excel file.
