Hi Joelle,

I can definitely help you with that! It sounds like the row numbers and column letters are hidden in your Excel document. Here's how you can unhide them:

1. Click on the "Tools" menu at the top of the screen.
2. Select "Options" from the drop-down menu.
3. Click on the "View" tab.
4. Make sure the "Row & Column Headers" option is checked.
5. Click "OK" to save your changes.

Once you've completed these steps, the row numbers and column letters should be visible again in your document.
