First off, I have no doubt this has been asked and answered many times but I cannot seem to get the answer by searching. Forgive me if I missed something obvious.

I am currently using Excel 2003. I have several workbooks which are entirely controlled by user-defined menus/toolbars to which are attached many, many macros and 1000's lines of code. Not just buttons to run a macro, but menus for selecting sheets and hiding/showing toolbars for that sheet. Some years ago I invested in 2007 but it could not emulate these setups, so I reverted to 2003.

My questions please......for Excel 2013 (if someone has a link covering this, please let me know)

1. will I be able to use the setups described above?
2. is the process of creating user-defined menus/toolbars very different to 2003?

Thanks, Peter
