In excel, there is a way to do x bar, but not x bar bar.
For x bar, you type the x, and then go to "Insert" and then to "Symbol". From here you locate the one that is labeled as the "COMBINING MACRON" and click it. It will put the line over the x.
Let me know if you figure out on for x bar bar. Doing this process twice does not work. I tried it already.
