I have a list of strings, printing out:

["TEST1","TEST2","TEST3"]

How would I go about transforming this data to this JSON formatting?

[
{
"value": "TEST1"
},
{
"value": "TEST2"
},
{
"value": "TEST3"
}
]

I do not plan on creating an object.

Have tried using dictionary and key value pairs as well.

>Solution :

you can try this

List<string> tests = new List<string> { "TEST1", "TEST2", "TEST3"};

string json = JsonConvert.SerializeObject( tests.Select( t=> new { value = t }));

but I highly recommend to create a class

string json = JsonConvert.SerializeObject( tests.Select( t => new Test { value = t}));

   // or if you are using System.Text.Json
string json = JsonSerializer.Serialize(tests.Select(  t=>n ew Test { value = t }));
    
public class Test
{
    public string value {get; set;}
}

json

[{"value":"TEST1"},{"value":"TEST2"},{"value":"TEST3"}]
