Hi there!

Adding slashes to dates in Excel is a quick and easy process. Here's how you can do it:

1. Select the column that contains the dates you want to format.
2. Right-click on the selected cells and choose "Format Cells" from the drop-down menu.
3. In the "Format Cells" dialog box, select "Custom" from the list of categories on the left.
4. In the "Type" field on the right, enter the following format code: "m/d/yyyy" (without the quotes).
5. Click "OK" to apply the new format to the selected cells.

That's it! Your dates should now be formatted with slashes in the desired format.

If you want to apply this format to a single cell, you can simply type the date in the desired format (e.g. 7/13/2007) and Excel will recognize it as a date and format it accordingly.
