What steps should I take to automatically apply a new date format to existing data in Excel?

To automatically apply a new date format to existing data in Excel, you can use the following steps:

1. Select the cells or range of cells that contain the dates you want to reformat.
2. Right-click on the selected cells and choose Format Cells from the context menu, or go to the Home tab and click on the small arrow in the Number group.

2. In the Excel Options dialog box, go to the Advanced tab.
3. Scroll down to the Editing options section and click on Edit Custom Lists.

6. Click Add and then OK to close all dialog boxes.

This will make the new format the default for any new cells that you format as dates.
