Don't worry, I can definitely help you with that! It sounds like you're referring to the formula bar in Excel. Here's how you can get it back:

1. Look for the "View" tab in the top menu bar of Excel.
2. Click on "View" and then look for the "Show" section.
3. Make sure that the "Formula Bar" option is checked. If it's not, click on it to enable it.

Once you've done that, the formula bar should reappear at the top of your Excel window. You can use it to enter formulas and text into cells, just like before.

If for some reason this doesn't work, you can also try pressing the "Ctrl" + "Shift" + "U" keys on your keyboard to toggle the formula bar on and off.

I hope that helps!
