Is there any way to format all script documents without going in each one individually?
You can search in the Toolbox for plugins that are related to formatting code. 
Yes, you can use Ctrl+Shift+F.
-
Write a code inside the textbox, like an example can be print(“hiii!”)
This will found all scripts with print(“hiii!”)
Click the 2 arrows at the left.
-
Now in replace you can choose what write instead of print(“hiii!”), I am going to write print(“wow!”)
I will click Replace all, and done!
This will replace all scripts that has print(“hiii!”)
