[File] Question Regarding is_json.c

[Puvipavan]

Thanks a lot for the quick response. Looks like I'm using a bit older

$ file test.json
test.json: ASCII text

$ file --version
file-5.38
magic file from /etc/magic:/usr/share/misc/magic

$ cat test.json
[
    {
        "id": "123",
        "labels": []
    }
]
