How to Unmerge Cells in Excel - Practical Guide

Learn how to unmerge cells in Excel to separate combined cells back into individual ones. This essential formatting skill helps restore data structure, improve spreadsheet organization, and prepare data for sorting or analysis. Unmerging is crucial when working with templates or inherited spreadsheets that contain merged cells limiting functionality.

Why This Matters

Merged cells often restrict sorting, filtering, and formula calculations, making unmerging essential for proper data management. Separating cells improves spreadsheet functionality and compatibility with data analysis tools.

Prerequisites

•Basic Excel knowledge and ability to select cells
•A spreadsheet containing merged cells
•Understanding of cell selection and the Ribbon interface

Step-by-Step Instructions

Open your spreadsheet

Launch Excel and open the file containing merged cells you want to unmerge.

Select the merged cell(s)

Click on the merged cell or drag to select multiple merged cells across your spreadsheet.

Access the merge cells option

Go to Home > Merge & Center > Unmerge Cells in the Ribbon toolbar.

Click Unmerge Cells

Click the Unmerge Cells button to immediately separate the selected merged cells into individual cells.

Verify the results

Review the unmerged cells to confirm they've been properly separated and the data is intact.

Alternative Methods

Using the Format Cells dialog

Right-click the merged cell, select Format Cells, go to Alignment tab, and uncheck 'Merge cells' option. This method provides additional formatting control simultaneously.

Keyboard shortcut via dialog

Tips & Tricks

✓Select all merged cells at once using Ctrl+A to unmerge the entire sheet in one action.
✓When unmerging, Excel retains data only in the top-left cell; other cell positions become empty.
✓Use Find & Replace (Ctrl+H) to quickly locate and select merged cells before unmerging.

Pro Tips

★Before unmerging, copy merged cell content to a separate location if you need to preserve all data across multiple cells.
★Use conditional formatting after unmerging to quickly identify empty cells that previously contained merged data.
★Create a backup before unmerging large sections to easily revert if the data structure changes unexpectedly.

Troubleshooting

Unmerge Cells button is grayed out

Ensure you've selected a merged cell and not regular cells. If still grayed out, check that you have edit permissions on the workbook.

Data disappeared after unmerging

Excel retains data only in the top-left cell of merged ranges; use Undo (Ctrl+Z) immediately if critical data was lost, then copy data before unmerging.

Cannot unmerge protected cells

The sheet may be protected. Go to Review > Unprotect Sheet and enter the password if required, then attempt unmerging again.
