What is wrong with google docs?

I created an excel spreadsheet in Google docs with several fields. However at the moment It will only open up part of the spread sheet and also the menu bar is not working as well. I have been trying to fix for a while now I even shut down and restarted the computer and that did not fix my problems. Does anyone know what could be the cause and how to fix it ?|||Maybe you could try using a different browser like firefox, chrome, opera or internet explorer also try clearing the cache the easiest way to do it is by going to opciones y and pressing the privacy tab then just click wipe cache or download the cleaner i use.|||everything
