Convert list of values to a key value json - json

Question

I'm trying to convert a list comma separated IP values (192.168.1.1,192.168.1.2,192.168.1.3, xxxx,xxxx) to a key value json so that at the end of all I can have a file with the structure below.
{
"ips": [
{
"ip": "192.168.1.1"
},
{
"ip": "192.*.*.*"
},
{
"ip": "192.168.1.3/32"
}
]
}
I was trying to user the command ConvertTo-Json command form powershell but really don't manage how to get it.
Home anyone can give me a hand and guide me how to handle this issue
Thanks you very much

Answer 1

Create objects or hashtables with the same contents and structure as your desired JSON, then pipe to ConvertTo-Json:
#{
'ips' = #(
#{ "ip" = "192.168.1.1" },
#{ "ip" = "192.*.*.*" },
#{ "ip" = "192.168.1.3/32" },
)
} |ConvertTo-Json |Set-Content path\to\output.json
Now you just need to generate the inner hashtables from a list instead of hardcoding them:
$listOfIPs = '192.168.1.1,192.*.*.*,192.168.1.3/32' -split ','
#{
'ips' = #(
$listOfIPs |ForEach-Object { #{ "ip" = $_ } }
)
} |ConvertTo-Json |Set-Content path\to\output.json
