You beat me to it. I used .object and .str:

import std;

void main()
     JSONValue data = parseJSON(`{ "name": "Hype Editor", "hobby": 
"Programming" }`);
     writefln("%s", data);

     // This already sees the data as an AA but the type is 
     auto o = data.object;
     static assert(is(typeof(o) == JSONValue[string]));

     writeln("Accessing the data with .str:");
     foreach (key, jsonValue; o) {
       writeln("  ", key, ": ", jsonValue.str);

     // If that much is not sufficient, you can convert it to a
     // proper AA like this:
     auto aa_data = o
                    .map!(kv => tuple(kv.key, kv.value.str))
     static assert(is(typeof(aa_data) == string[string]));

     writeln("Now it's string[string]:");
     writefln("  %s", aa_data);
