How to create multiple secrets from a json file

I looking for a solution where I can create multiple secrets through a JSON file. Like I have a path in my vault /dev
in dev account running more the 40 applications. So is there any way to create 40 keys and their respective data for all 40 applications using a single JSON file.

[
“Keys”: “xyz”,

{
    "secret1": "xyz",
    "secret2":"abc"
}   

]

Did you check documentation?
