XLS download and replace - format completely messed up

I downloaded the XLS file from the online form builder to add images into 2 questions as note, I did not touch the rest of the XLS and when I replaced it, the online form is completely messed up and unformatted. It has codes coming up, hashtags etc. What did I do wrong and how can I fix it?
