How to Unmerge Cells in Excel (Shortcut + Keep Data)

To unmerge cells in Excel, select the merged cell and go to Home > Merge & Center > Unmerge Cells. The merged cell splits back into its original cells.

Here’s the quick version:

  1. Select the merged cell (or a range with several merged cells).
  2. On the Home tab, in the Alignment group, click the arrow next to Merge & Center.
  3. Click Unmerge Cells.

Prefer the keyboard? Press Alt, H, M, U one key after another.

After unmerging, the content stays in the upper-left cell and the other cells are empty. Below, I’ll also show you how to unmerge all cells at once and how to fill the empty cells with the value after unmerging.

Merging cells joins two or more adjacent cells into one larger cell. Unmerging splits them back into their original pieces.

How to unmerge cells

Let’s say you have this sheet where you mistakenly merged A2 and B2:

jan to april only 2019 monthly sales

As you can see, B2 should say “Sales”.

But before you can do anything, you will have to unmerge the merged A2B2 cell first.

To do so, make sure the merged cell is selected. Also, check that you’re in the ‘Home’ tab.

home tab on tab list

Under the ‘Alignment’ group on the Ribbon, click the ‘Merge & Center’ icon. Merge & Center works like an on/off switch, so clicking it on a merged cell unmerges it. You can also click the small arrow next to it and choose Unmerge Cells.

If the cell you’re unmerging is merged, the icon will have a gray background like it’s being pressed.

After that, the cell will now break into A2 and B2. The text “Month” stays in A2, the upper-left cell, and B2 is empty.

From there, we can now make changes to B2 without affecting A2.

Unmerge cell key combination

There’s a key combination that would let you unmerge a cell without moving your mouse.

Of course, the cell has to be selected first before the unmerging can take place.

Take note that ‘unmerge’ doesn’t have a Ctrl shortcut. This key combination uses the ribbon’s key tips: the letters Excel shows when you press Alt.

  • Alt: shows the key tips on the ribbon
  • H: opens the Home tab
  • M: opens the Merge & Center menu
  • U: picks Unmerge Cells

When putting together everything, all you have to do is press Alt, then H, then M, then U, one key after another. You don’t need to hold Alt down.

The same key tips work for merging: Alt, H, M, C is Merge & Center and Alt, H, M, M is Merge Cells.

Unmerge all cells at once

Got a sheet full of merged cells? You don’t have to unmerge them one by one.

  1. Select the whole sheet: press Ctrl + A (press it twice if your cursor is inside a data range), or click the Select All button (the small triangle in the top-left corner where the row numbers and column letters meet).
  2. Go to Home > Merge & Center arrow > Unmerge Cells (or press Alt, H, M, U).

Every merged cell on the sheet is unmerged in one go.

Want to see where the merged cells are first?

  1. Go to Home > Find & Select > Find.
  2. Click Options > Format.
  3. On the Alignment tab, check Merge cells and click OK.
  4. Click Find All to see a list of all merged cells in the sheet.

This is handy because Excel can’t sort a column that contains merged cells.

Unmerge and keep the data in every cell

When you unmerge cells, only the upper-left cell keeps the value. The rest are empty. If you need the value repeated in every cell (for example, to sort, filter or use the data in a PivotTable), do this right after unmerging, while the cells are still selected:

  1. Go to Home > Find & Select > Go To Special.
  2. Choose Blanks and click OK. Now only the empty cells are selected.
  3. Type = and press the Up Arrow key once. The formula now points to the cell above. (If the cells were merged across columns, press the Left Arrow key instead.)
  4. Press Ctrl + Enter to put the formula in all the selected blank cells at once.

Every empty cell now shows the value from the cell above it. To turn the formulas into fixed values, copy the range and paste it as values. Here’s how to copy values instead of formulas.

Tip: If you only merged cells to center a title across columns, use Center Across Selection instead. Select the cells, press Ctrl + 1, and on the Alignment tab choose Center Across Selection under Horizontal. It looks the same as Merge & Center, but every cell stays a normal cell. More on that in my guide to merging cells in Excel.

Wrapping things up…

In a sense, it’s a simple two-step process: select cell and click the icon. That’s it!

Knowing how to unmerge cells is easier than knowing how to open Microsoft Excel for the first time. 😊

How do I split a cell in Excel?

You can only split a cell that was merged before (by unmerging it). A normal cell can’t be split into two cells. To split the text in a cell across columns, use Data > Text to Columns. Here’s my guide on how to split a cell in Excel.

Does this work in Excel for Mac and Excel for the web?

Yes. In both, select the merged cell and choose Unmerge Cells from the Merge & Center menu on the Home tab.
