It might be to your benefit to create a Macro. Using Macros can help automate your more commonly used edits. Recording a Macro while editing one cell will allow you to replay the macro and automate the same edit steps on other cells.
Caution, if you change cell locations while recording a macro, replaying the macro will take you back to this location. If you want to replay the Macro on different locations, you will need to pick the location for recording the Macro before you start the recording.
Once you learn how Macros work and study the code used, you can then start programing your own code. If you learn how to program your own code, you could then automate the entire process of editing your page.
