How to merge and unmerge cells in Microsoft Excel

Microsoft Excel is a powerful application, capable of acting as a full-featured spreadsheet and data analysis tool. While Excel is fully capable of some powerful data manipulation tasks, sometimes you need to do something simple like merge and unmerge cells. That essentially means placing the value of one into multiple cells or two cells into a single cell. That's exactly what we're going to cover in this how-to.

Using the Merge and Center command to merge cells

The easiest way to merge a single cell into multiple cells is using the Merge and Center command from the main menu. This command takes the value in the left-most cell in left-to-right languages or the right-most cell in right-to-left languages and places it into however many cells are selected. It's particularly useful when you want a column header to cover multiple columns, such as in the sample spreadsheet where we would like the "Q1 Sales" title to refer to all of the first quarter months.

Step 1: Select the cells you want to merge into and click on the Merge and Center command.

Step 2: If you simply click on the Merge and Center button, then the "Q1 Sales" will be spread across the three cells and centered. Note that any data in the cells to the right will be overwritten.

Step 3: You can also select Merge Across and the cells will be merged but the content will be moved to the left. The Merge Cells function will do the same in most cases.

Using the Merge Cells command to unmerge cells in Microsoft Excel

It's easy enough to unmerge cells that you've merged using the Merge Cells command.

Simply select the cells you wish to unmerge, and select Unmerge Cells from the drop-down menu.

Using the Concatenate function to merge cells in Microsoft Excel

Sometimes we want to take two columns and merge them into one, keeping the information from both columns. In our sample spreadsheet, we'd like to take the first name and last name and combine them into a cell containing the full name.

This is easily done by using the Concatenate function. We create the formula in the cell where we want the full name to populate. The formula is in the format "=CONCATENATE(A1," ",B1), where A1 refers to the left-most cell, B1 refers to the right-most cell, and the middle section indicates that we want the data separated by a space. We could use any symbol we like here. Note that any data in the column where the data is to be merged will be overwritten.
