Yes, you can quickly format the Postal Code column to include the space using the following steps:

1. Select the entire column that contains the Postal Codes.
2. Right-click on the selected column and choose "Format Cells" from the drop-down menu.
3. In the "Format Cells" dialog box, select "Custom" from the Category list.
4. In the "Type" field, enter the following format: L0L 0L0 (where "L" represents a letter and "0" represents a number).
5. Click "OK" to apply the new format to the selected column.

This should add the space between the first and last 3 characters of each Postal Code in the column. If you have any issues with this process, feel free to ask for further clarification.
