Change one value and save

[yates6460]

I have this json file which I want to change one value and save it, multiple times. How do I start?

I want to change to email with another email and save the file as “email”.json and repeat with another email.
Can I do this in SUBLIME or any other program or it is impossible?
P.S I have the emails in a csv file.

A repetitive change operation like this is probably best done with a more purpose made tool like a script of some kind, unless you only have a small handful of versions of the file that you want to create.

A custom script of some sort is probably the easiest way (all things being equal); Sublime could be made to do this as well with an appropriate custom plugin, but I’m not aware of any offhand that would do something like this.
