Hello and thank you in advance for the help!

I am currently working with a worksheet that shows data. When i double
click on the data, an excel chart pops up in another sheet. This was done
using vba. I'd like to make the data worksheet a little more interactive.
When the user is pointing the arrow over a cell, i'd like the font or
something to change to show the user that something could happen if he/she
decides to click on the cell.

Can i use vb or javascript to achieve this and what is the code for it?
