Trim Cell Range Example

Select the desired Range of cells and apply Trim method on it. This method trims leading and trailing empty cells from the selected range.

Tips

The Trim method does not remove empty cells located in the middle of rows and columns within the range. To address this, you can apply sorting to push those empty cells to either top or bottom of the range.
