Is there a way to conver vector<string> with entry key-vaule pair(ex. ["name:John", "Age:20"]) to json?)

[YunlongB]

Hey There,
I am wondering If there exist a direct way to convert the vector to json, a example of vector is ["name:John", "Age:20", "Gender: male"] each string contains a key vaule pair that separated by colon.
Appreciate
