Well, how do you unmerge cells in Excel to get things back to normal? Below, you will find a few simple techniques. Filtering or even selecting a range might also be a problem. For example, you cannot sort data in columns that have at least one merged cell. So, you merge a few smaller cells into a bigger one only to realize that merged cells have made it impossible to perform the simplest tasks on your worksheet. When you have related data in several cells, you may be tempted to combine them into a single cell for alignment or comparison purposes. This short tutorial shows how to quickly unmerge cells in Excel, how to find all merged cells in a worksheet, and how to fill each unmerged cell with the original value from the merged cell.
