j2pb -f test.json -o test.proto does the same thing but save the result in test.proto

And you can use json2pb in your project just by adding json2pb="*" in your cargo dependency.

use json2pb::pbgen;
use nom::error::VerboseError;

let json_code = r#"
    {
        "name": "deen",
        "age": 26
    }
"#;

let (_, json_value) = parser::root::<VerboseError<&str>>(json_code).unwrap();
let json_2_pb_ast = pbgen::visit_json_root(&json_value).unwrap();
let generated_pb_message = pbgen::gen_pb_def(&json_2_pb_ast);
assert_eq!(generated_pb_message, r#"message root_data {
    string name = 1;
    int64 age = 2;
}
"#);
