I don’t know how to do this

I have not tried anything yet, I don’t even know where to start to be honest I am new to coding and was curious to see how this would work, if someone can put me in the right direction of how to at least learn what I want to achieve that would be great but any help is appreciated. again i just want someone for example to have a .json file of some of their info and for them to be able to copy n paste it into the IPA files and for it to appear onto the screen
