Merge and unmerge cells in Excel for Mac

Merging combines two or more cells to create a new, larger cell. This is a great way to create a label that spans several columns.

In the example here, cells A1, B1, and C1 were merged to create the label “Monthly Sales” to describe the information in rows 2 through 7.

Merge cells

Merge two or more cells by following these steps:

  1. Select two or more adjacent cells you want to merge.

    Important: Ensure that the data you want to retain is in the upper-left cell, and keep in mind that all data in the other merged cells will be deleted. To retain any data from those other cells, simply copy it to another place in the worksheet—before you merge.

  2. On the Home tab, select Merge & Center.
    On the Home tab, select Merge & Center


  • If Merge & Center is disabled, ensure that you’re not editing a cell—and the cells you want to merge aren’t formatted as an Excel table. Cells formatted as a table typically display alternating shaded rows, and perhaps filter arrows on the column headings.

  • To merge cells without centering, click the arrow next to Merge and Center, and then click Merge Across or Merge Cells.

Unmerge cells

If you need to reverse a cell merge, click onto the merged cell and then choose Unmerge Cells item in the Merge & Center menu (see the figure above).

Split text from one cell into multiple cells

You can take the text in one or more cells, and distribute it to multiple cells. This is the opposite of concatenation, in which you combine text from two or more cells into one cell.

For example, you can split a column containing full names into separate First Name and Last Name columns:

Before and after of text split into different columns

Follow the steps below to split text into multiple columns:

  1. Select the cell or column that contains the text you want to split.

  2. Note: Select as many rows as you want, but no more than one column. Also, ensure that are sufficient empty columns to the right—so that none of your data is deleted. Simply add empty columns, if necessary.

  3. Click Data >Text to Columns, which displays the Convert Text to Columns Wizard.

  4. Click Delimited > Next.

  5. Check the Space box, and clear the rest of the boxes. Or, check both the Comma and Space boxes if that is how your text is split (such as "Reyes, Javiers", with a comma and space between the names). A preview of the data appears in the panel at the bottom of the popup window.

    Step 2 in the wizard, Under Delimeters, pick how your data is split; Under Preview, you can see a preview of your data

  6. Click Next and then choose the format for your new columns. If you don't want the default format, choose a format such as Text, then click the second column of data in the Data preview window, and click the same format again. Repeat this for all of the columns in the preview window.
    Step 3 in the wizard, Text option selected

  7. Click the Collapse Dialog Box button image button to the right of the Destination box to collapse the popup window.

  8. Anywhere in your workbook, select the cells that you want to contain the split data. For example, if you are dividing a full name into a first name column and a last name column, select the appropriate number of cells in two adjacent columns.

    Select the cells where you want to paste your split cells

  9. Click the Expand button button to expand the popup window again, and then click the Finish button.
