Parsing dynamic json in go

I am trying to parse the following json structure, where the fields marked with "val1" and "val2" are constantly changing, so I cannot use a predefined struct. How could I parse this json in a way to be able to loop through every single "val"? Thank you!

{"result":true,"info":{"funds":{"borrow":{"val1":"0","val2":"0"},"free":{"val1":"0","val2":"0"},"freezed":{"val1":"0","val2":"0"}}}}


struct { Borrow, Free, Freezed map[string]interface{} }

By unmarshalling into the following struct I can loop through the desired fields.

type Fields struct {
Result bool `json:"result"`
Info struct {
Funds struct {
Borrow, Free, Freezed map[string]interface{}
} `json:"funds"`
} `json:"info"`
}


package main

import (
"fmt"
"encoding/json"
)

type Root struct {
Result bool `json:"result"`
Info Info `json:"info"`
}

type Info struct {
Funds struct {
Borrow, Free, Freezed map[string]interface{}
} `json:"funds"`
}

func main() {
var rootObject Root
jsonContent := " {"result":true,"info":{"funds":{"borrow":{"val1":"0","val2":"0"},"free":{"val1":"0","val2":"0"},"freezed":{"val1":"0","val2":"0"}}}}"

if err := json.Unmarshal(byte(jsonContent), &rootObject); err != nil {
panic(err)
}
fmt.Println(rootObject)
}
